    题 目:填隙幂律流体下湿颗粒间作用的离散元模型

    主讲人:徐泳,中国农业大学

    提 要:

    湿颗粒群是密相颗粒和填隙流体的混合结构,流体呈液桥状或浸渍态存在于颗粒之间,如湿土和冰淇淋等。它不同于干颗粒群和有显性流动的二相流,不适合按固-流耦合建立离散元模型。填隙流体下湿颗粒间作用的离散元模型是基于Reynolds润滑理论对流动模型进行定常简化后求得简单的解析或数值解,仿照干颗粒作用模型建立的。练国平等基于Reynolds润滑理论建立了牛顿流体湿颗粒作用模型,在两个接近的刚性球间有法向和切向相对运动时,只考虑因流体粘性在接触局部的缝隙产生的法向力和切向力,法向力包括液桥张力和挤压流动的法向粘性力。

    对球间有幂律流体时的法向作用,Rodin用渐近法得到对任意球体的分段不连续解。徐泳等以Adams两等径圆球间有填隙幂律流体时的分分析,导出了任意球体间挤压力的表达式并提出拟合公式。Lian等进一步给出近似封闭解。幂律流体下球间的切向作用因非轴对称更复杂。黄文彬、李红艳等采用小参数法导出了压力方程,得到切向阻力的解析解。这两方面作用的研究为非牛顿流体下的湿散体的离散元模拟提供近似模型和算法,其适用性还需要进一步验证。

    题 目:针对边坡有效管理的可靠度模拟(Performance Based Modelling of Slope Reliability for Effective Slope Management)

    主讲人:Wilson H Tang教授,香港科技大学土木系

    提 要:

    像许多其它山区一样,香港受到严重暴雨期间滑坡的威胁。城市区人工切坡的安全性成为主要问题。然而,目前边坡工程可靠度分析中,有关各种服务期边坡可靠性的衰退,还没有得到明晰的考虑。实际中,普遍使用的评价给定服务期内的边坡可靠性的,并作为常数的年破坏概率,不能够反映边坡衰退特征。本讲座将介绍一种能够概率模拟破坏概率随时间变化的这类衰退效应的方法。我们系统地分析了香港地区大量边坡的已有性状,并将这种分析用于计算不同年龄、不同期望服务期的各类边坡的破坏概率。通过这些工作,不同服务期内的不同年龄的边坡的可靠度,得到了合理预测。这些结果将对香港地区成千上万现存的老边坡的日常维护计划等各类工作非常有帮助,同时也可用于比较运用不同标准设计的边坡的性能。

    先前的概率主要是政府部门的规划者,为了滑坡灾害管理,而对边坡的可靠度进行的全局估计。对于具体的项目来讲,需要的是更为精确的针对场地的破坏概率。在这种情况下,通常都用标准的可靠度分析来精确估计可靠度指标,当然这需要借助于其它特定场地的资料。然而,此类破坏概率仍然受到所采用的确定性和概率模型本身的限制,相应的结果也不反映衰退效应的自然属性。此时,所观察到的边坡实际行为能够再次提供信息,用于消除自然而然产生的模型误差,而校准所计算的破坏概率。基于Bayes方法,边坡的实际行为、系统衰退效应和其它未被考虑到的因素,能够系统地耦合在一起,将给定边坡的所计算的可靠度指标转换到边坡真实破坏概率的估计上来。

    这种破坏概率将校正高估或低估了的计算破坏概率。同时,先前估计的全局破坏概率,能够用作额外的先验信息,来给出全部校准的破坏概率。之后,进一步提供了一种方法,用于评价了与校准破坏概率有关的不确定性,这种不确定性来源于所假定的概率模型、数据的充分性等因素。通过这种方法,一个给定边坡的可靠度估计及其置信区间,能够较好地服务于边坡维护改善、滑坡灾害管理等决策。

    Like many other places with a hilly terrain, Hong Kong has been subjected to threats of landslides when heavy rainstorms occur. The safety of man-made cut slopes in urban area is a major concern. The effect of deterioration on the reliability of slopes of various periods of service, however, has seldom been considered explicitly in the current reliability approach in slope engineering. Constant annual failure probabilities that are commonly used in practice to evaluate reliability of a slope over a given expected service period may not be capable of capturing the deteriorating characteristics of slopes. This presentation will describe a procedure to model probabilistically the deteriorating effect on the failure probability with time. Past performance of an extensive set of cut slopes in Hong Kong is systematically analyzed to evaluate the stability failure probabilities for slopes of different ages and for different expected service periods. Through this exercise, the reliability of slopes of different ages in different future service periods could reasonably be predicted. The results would be very useful for planning of maintenance and retrofitting works to the thousands of remaining old slopes in Hong Kong, and for comparing performance of slopes designed on different standards.

    While the previous probability would serve a global estimate of slope reliability to assist landslide hazard management by the government planners, a more accurate site-specific failure probability would be needed for an individual project. In this case, a formal reliability analysis is usually conducted with the benefit of the additional site-specific data to provide a more accurate estimate of the reliability index. However, the corresponding failure probability would still be limited by the deterministic and probabilistic model assumed, which may not necessarily represent the state of nature such as the deteriorating effect. Observed performances could again provide valuable information to calibrate this calculated probability for the model error that may have been accrued. Through a Bayesian procedure, performance records and effect of system deterioration and other unaccounted for factors can be systematically incorporated to convert the calculated reliability index of a given slope to an estimate of the real probability of failure.

    This probability will correct for the under or over conservatism of the true probability by the calculated reliability index. At the same time, the previous global estimate of failure probability can serve as additional prior information to yield the overall calibrated probability. A procedure is further introduced to assess the uncertainty associated with the calibrated probability, resulting from various factors including the assumed probabilistic models and the availability of performance records for calibration. Through this formulation, the reliability estimate of a given slope (of similar type and under similar environmental condition) and its associated confidence range can be realistically assessed to provide inputs for a more defensible decision regarding slope improvement and landslide hazard management.

    题 目:功能极限状态设计中的地基基础概率容许位移(Probabilistic Limiting Tolerable Displacements for Serviceability Limit State Design of Foundations)

    主讲人:张利民教授,香港科技大学土木系

    提 要:

    岩土工程设计需要同时满足极端的极限状态和功能极限状态要求。极限状态设计主要指各种功能要求,并要求考虑各种不确定性。目前,大多数极限状态设计规范,运用可靠度原理来对极端极限状态进行设计。然而,传统的确定性方法常常考虑功能极限状态。本讲座介绍一种基于功能考虑的,然而是在可靠度框架下的位移判据,并给出了限定的容许位移地概率分布。为了一致,此位移判据可以与极端状态下的位移判据进行对比。此判据既考虑了限制容许位移的不确定性,也考虑了期望荷载下的估计位移的不确定性。为了给出合适的限制容许位移地概率分布,研究了超过400个桥梁和300个建筑的观察位移及行为数据。借助于脆性曲线,分别建立了各种类型结构的限制容许位移和扭角的概率分布。运用所建立的基于可靠度框架的位移准则,和限制容许位移概率分布,极端极限和功能极限状态设计的理念将达成一致。

    The design of a geotechnical work should satisfy both the ultimate limit state and serviceability limit state requirements. The limit-state design approach addresses various performance requirements and aims to accommodate uncertainties. Presently, most limit-state design codes use reliability principles for designing for ultimate limit states. However, serviceability limit states are often considered using the conventional deterministic approach. In this talk, a reliability-based displacement criterion for serviceability considerations is introduced and probability distributions of the limiting tolerable displacements of structures are described. The displacement criterion is analogous to that for the ultimate limits for harmonisation purposes. It considers uncertainties in both estimated displacements under expected service loads and the limiting tolerable displacements.

    To formulate appropriate probability distributions of the limiting tolerable displacements, observed displacements and performance of over 400 bridges and 300 buildings are investigated. The probabilistic distributions of the limiting tolerable settlement and angular distortion for each type of the structures studied are then established by the use of fragility curves. With the establishment of the reliability-based displacement criterion and the probability distributions of the limiting tolerable displacements, the philosophies of limit-state design for both ultimate limits and serviceability limits would become more consistent.

    题 目:可靠度框架下的基础工程风险管理(Risk Management in Foundation Engineering in the Framework of Reliability-Based Design)

    主讲人:张利民教授,香港科技大学土木系

    提 要:

    本讲座试图将可靠度框架下风险管理运用于基础工程设计。为了易于进行风险管理,首先描述和罗列了基础工程设计和施工中的不确定性。接着,探讨了与许用应力法、基于可靠度的设计方法等两类常用的设计方法有关的安全水平。阐述了用于不确定性约减和风险管理的Bayes方法的基本原理,并给出了一个基础工程寿命期内的风险管理规划。最后,讨论了可靠度框架设计的研究和发展的意义。

    An attempt is made to lay a reliability-based framework for risk management in foundation engineering. First, uncertainties involved in foundation design and construction are described and organized to facilitate risk management. Then, safety levels associated with two common design approaches, i.e., the allowable stress design approach and the reliability-based design approach are examined. The principle of using the Bayesian approach for uncertainty reduction and risk management is described and illustrated. Subsequently, a risk management plan is depicted, which is targeted at effectively managing risks throughout the life cycle of a foundation. Finally, the value of research and development in the framework of reliability-based design is discussed.

    题 目:岩土工程中的Bayes方法

    主讲人:王建锋,中国科学院力学研究所

    提 要:

    经典的岩土工程统计分析中,都假定分布参数为常量,运用样本统计量对参数进行估计。这种估计不可避免有误差,并且精确的估计需要大量的样本。然而,岩土工程中,尤其是原位试验数据,由于费时和昂贵,数据量都极为有限。在这种情况下,参数的估计通常要依赖于工程经验。传统的统计方法,没有提供将工程经验与观察数据相结合的方法,而Bayes方法则能有效地解决此类问题。

    Bayes方法假定分布的未知参数是随机变量。参数估计方法本身带来的不确定性,可以通过Bayes定理与随机变量本身固有的变异性结合起来。基于这种处理方法,来源于主观的判断、经验或一些间接的信息,可以很好地与观察数据相结合,来获得分布参数的估计。方法本身主要涉及全概率事件、条件概率等概念和Bayes定理,其实质类似于“加权估计”。可以说,传统的“工程地质类比法”的定量化延伸。在有充分工程经验的岩土工程场合,Bayes方法更具有优越性。

    本讲座主要介绍Bayes方法的基本概念、原理,以及在桩基承载力、边坡稳定、场地勘探中的应用。
