摘要
在地质灾害防治设计中,重力式挡土墙是重要的方法之一,如何快速、简便、准确地选用符合实际情况的重力式挡土墙成为一个重要的课题。本文通过介绍影响重力式挡土墙稳定性的各种因素,按照规范规定计算了各因素影响下挡土墙的安全系数,利用敏感性分析的方法,逐个分析了各因素在重力式挡土墙稳定性中所起的作用,分析了各因素对挡土墙稳定性的影响程度,找出了影响挡土墙稳定性的主要因素,并提出了重力式挡墙设计中应当注意的各种问题,为重力式挡土墙的设计提供了可靠的依据。
Gravity retaining wall is one of the important means in geological disaster design. It is an important issue to select an most suitable gravity retaining wall quickly, easily and accurately. In this paper, the influence factors on gravity retaining wall stability are introduced, and the safe coefficient under the action of every factor is calculated according to the standard. The influence degree of every factor is analyzed one by one using sensitivity analysis method, and the main factor is found. All kinds of problems in design that should be paid attention are forward. The study could be a reliable reference for gravity retaining wall design.
