基于弹性理论设计边坡防护方法研究

边坡防护设计主要是通过边坡稳定性分析，找到稳定系数最小部位（称为最危险滑动面），然后根据边坡稳定系数要求，计算稳定系数及下滑力，设计所需边坡防护。这种分析方法是把边坡土体假定为刚塑性体，再划分为较小单元，略去影响较小因素后，进行力学平衡分析，最终确定稳定系数和防护形式。然而，边坡岩土体并非理想刚塑性体，边坡的开挖过程是对原有平衡的破坏，而边坡防护则是重新建立这种平衡状态。如何通过边坡防护构建坡体系统平衡或恢复原有平衡系统，是边坡防护要解决的首要问题。采用弹性理论方法计算边坡应力状态，可为建立新的平衡体系提供计算依据。

Research on design of slope protection methods based on elasticity theory

The slope protection design is mainly based on the slope stability analysis to find the position with the minimum stability coefficient (called the most dangerous sliding surface),and then calculate the stability coefficient and sliding force according to the requirements of the slope stability coefficient to design the required slope protection.This analysis method assumes that the soil mass of the slope is a rigid plastic body,and then divides it into smaller elements.After omitting the minor factors,the mechanical balance analysis is carried out,and the stability coefficient and protection form are finally determined.However,the rock and soil mass of the slope is not an ideal rigid plastic body.The excavation process of the slope is the destruction of the original balance,and the slope protection is to reestablish this balance.How to build the slope system balance or restore the original balance system through slope protection is the primary problem to be solved in slope protection.The elastic theory method is used to calculate the stress state of the slope,which can provide the calculation basis for establishing a new equilibrium system.
