基于瑞典圆弧法的基坑开挖边坡稳定性分析

Analysis of Foundation Pit Excavation Slope Stability Based on Swedish Circle Method

瑞典圆弧法是一种常用于计算边坡稳定性比较精确的方法,其基本原理是将边坡分为若干个圆弧段,然后分别计算每个圆弧段的稳定性,最终得出整个边坡的稳定性。该方法需要掌握一定的力学和数学知识,且需要对土体的力学性质、水文特征等进行详细的调查和分析。在实际工程中,通常需要借助计算机辅助进行计算。本文结合工程实例采用瑞典圆弧法对基坑稳定性进行评价分析。

Swedish circle method is a precise method commonly used to calculate the slop stability,and its basic principle is to divide the slope into several arc segments,and then calculate the stability of each arc segment separately,and finally obtain the stability of the whole slope.This method requires certain knowledge of mechanics and mathematics,and needs to conduct detailed investigation and analysis of the soil mass mechanical properties and hydrological characteristics.In actual projects,computer-aided calculations are usually required.In this paper,Swedish circle method is used to evaluate and analyze the foundation pit stability based on project examples.
