排水是治理滑坡的一种有效方法。为了提高排水系统的效率和可持续性，提出了一种新的虹吸排水方法。采用Morgenstern-Price法计算了虹吸排水设计方案作用下的安全系数，并对设计方案的有效性进行了评价。基于稳健设计思想，建立了虹吸排水新方法的设计指导思想。信噪比是FOS的均值和标准差的函数，与滑动面抗剪强度参数的不确定性有关，被用作设计稳健性的度量。基于稳健设计的概念，提出了一个框架，以确定最佳的虹吸排水设计考虑多个目标，包括安全，成本，设计稳健性，排水效果。本文以浙江省红埔村滑坡为例，说明了该框架的合理性。根据研究结果，得出最优虹吸排水设计方案。
Drainage is a critical and cost-effective method to stabilize rainfall-induced landslide. In order to improve the efficiency and sustainability of drainage system, a new siphon drainage method is presented in this paper. Factor of safety (FOS) under the action of a given siphon drainage design, computed using Morgenstern-Price method, was used to evaluate the design effectiveness. A guidance for the design of this new siphon drainage method was established based on the robust design concept. Signal-to-noise ratio, which is a function of mean and standard deviation of FOS and related to the uncertainty of shear strength parameters of slip surface, is used as a measure of the design robustness. A framework based on the concept of robust design is proposed for determining the most optimal siphon drainage design considering multiple objectives including safety, cost, design robustness, and drain effectiveness. This framework is illustrated with a case study, the Hongpucun landslide in Zhejiang Province, China. Based on the outcome of this study, the optimal siphon drainage design is obtained.
