摘要
考虑膨胀土的开裂性,研究了雨水入渗条件下的膨胀土边坡的渗流规律,进行了相对应的稳定性分析。通过考虑和不考虑裂隙时的膨胀土边坡稳定性的比较,表明二者具有很大的差异性。通过与现场实际情况相比较说明,在研究降雨入渗条件下的膨胀土边坡稳定性时,考虑土体的开裂性是十分必要的。
Considering the cracking of expansive soils,seepage characteristics of expansive soil slope are studied under circumstance of rainfall infiltration.Numerical analyses on slope stability are conducted accordingly.Simulation results show that there are obvious differences between numerical simulations with and without considering cracks in expansive soils.The field tests and numerical analyses show that it is essential to include the crack condition in the stability analysis of expansive soil slope with rainfall infiltration.
