不同降雨持续时间的组合结构支护边坡稳定性分析
Stability Analysis of Combined Structure Supporting Slope with Rainfall Duration
摘要
Abstract
Composite structure is widely used in slope support engineering.Combined with a combined structure supporting slope project,the numerical simulation method is used to analyze the indexes of the combined structure supporting slope under different rainfall duration.The results show that:(1)Under continuous rainfall conditions,the volume water content of slope foot is large,and attention should be paid to slope drainage and appropriate drainage methods;(2)The pore water pressure of slope foot is large,and the side slope foot should be paid attention to when supporting slope under similar rainfall conditions.(3)After the combined structure support,the plastic strain and displacement of the slope are significantly reduced,and the stability safety factor of the slope is significantly increased.When there was no rainfall,the stability safety factor increased by 40.2％,and the continuous rainfall for 12 h could still increase by 28.4％.The above research results have reference significance for similar slope support engineering.关键词
