大量研究认为,渗流对坡面侵蚀有着重要的影响,但是目前尚缺乏系统的实验或成熟的理论成果以反映渗流对坡面侵蚀的作用机理。针对坡面流-渗流共同作用下斜坡土体搬运过程的试验难题,提出专门实验装置及试验方法,通过观测坡面薄层水流侵蚀现象(片蚀)揭示渗流对薄层水流侵蚀的影响机理,为坡面侵蚀的预测预报及其防治提供有力的理论依据。基于ABAQUS软件进行有限元渗流计算分析,结果表明采用该试验方法后坡面上渗流不均匀度可控制在3%以内,证实了该研究方法的可行性。
Numerous studies show that seepage has an important influence on slope erosion, but there is no systematic experimental or mature theoretical result to reflect the mechanism of seepage on slope erosion. Aiming at the problem of slope soil-seepage flow handling process, a special experimental device and test method are proposed. By observing the phenomenon of thin-layer flow erosion (sheet erosion) on slope surface, the influence mechanism of seepage on thin- It provides a strong theoretical basis for the prediction and control of slope erosion. Based on ABAQUS software, the seepage calculation of finite element method is carried out. The results show that the seepage flow on the slope can be controlled within 3% after using this method, which proves the feasibility of this method.
