摘要:
广东山区残积土边坡广泛分布，同时由于当地居民大量削坡建房，破坏了自然残积土边坡的稳定性，在降雨的诱发条件下，极易发生边坡失稳破坏，引发地质灾害，造成人员伤亡。因此，研究削坡建房对残积土边坡稳定性的影响具有重要意义。基于粤东山区一典型红色砂岩残积土边坡，通过室内试验得到土体物理力学参数，采用有限元数值模拟方法及强度折减法进行边坡稳定性分析，研究在无雨、梅雨及暴雨条件下，不同削坡坡度、削坡坡高对红色砂岩残积土边坡稳定性的影响，得到了山区居民削坡建房时削坡坡度和削坡坡高的限值，为山区残积土边坡地质灾害防治工作提供参考依据。
Abstract:
The slopes of residual soil in the mountainous areas of Guangdong are widely distributed， and at the same time， due to the large number of local residents cutting slopes to build houses， the stability of the natural residual soil slopes is destroyed. Under the conditions induced by rainfall，it is very easy to occur slope instability and damage， causing geological disasters and casualties. Therefore， it is of great significance to study the influence of slope cutting and building on the stability of the slope of residual soil. Based on a typical red sandstone residual soil slope in the mountainous area of eastern Guangdong Province， the physical and mechanical parameters of the soil body are obtained through laboratory tests， and the slope stability is analyzed by using the finite element numerical simulation method and intensity reduction method. The influence of different slope cutting slopes and slope cutting heights on the slope stability of red sandstone residual soil under the conditions of no rain， plum rain and heavy rain were discussed. The limit values of slope cutting slope and slope cutting height of slope cutting slopes were obtained when the residential buildings were built by slope cutting，which provides a reference for the prevention and control of geological disasters of residual soil slope of mountain residual.
