摘要
在持续强降雨条件下,槐梁子滑坡发生显著的变形,对居民的生命财产安全构成了严重威胁。基于详细的地质调查,通过构建基于有限差分法的滑坡数值模型,采用渗流-应力耦合分析,研究不同降雨工况下滑坡的渗流场及位移场的演化特征及稳定性变化。结果表明,槐梁子滑坡在自然条件下处于基本稳定状态,但在强降雨等外部不利因素的作用下,滑坡中前部位移明显。尤其在连续暴雨的条件下,坡体孔隙水压力增加明显,滑坡发生整体滑动的可能性很大。研究结果为类似滑坡的预警、治理工程提供重要的理论依据。
The Huailiangzi landslide has experienced significant deformation under continuous heavy rainfall,posing a serious threat to the safety of residents’lives and property.Based on detailed geological surveys,a landslide numerical model was constructed using the finite difference method and a coupled seepage-stress analysis approach was employed to investigate the stability of the landslide,as well as the evolution characteristics of the seepage field and displacement field under different rainfall scenarios.The results show that the Huailiangzi landslide is generally stable under natural conditions.However,under the influence of external adverse factors such as heavy rainfall,the stability of the slope significantly decreases.In particular,under continuous rainfall,the increase in pore water pressure is substantial,significantly increasing the likelihood of overall landslide movement.The findings provide important theoretical support for early warning systems and mitigation engineering of similar landslides.
