摘要:
进行了室外天然降雨和室内人工降雨边坡模型试验,试验所用土料为海口美兰区粉土,室内和室外试验设置裸土、肾蕨、细叶结缕草三种边坡模型。模型的监测系统能够实时收集测量坡体内部的土壤含水率。通过两次室内人工模拟降雨和室外天然降雨,对比了三种不同植被边坡模型内部土壤含水率的变化。结果表明,边坡植被主要通过拦截降雨形成地表径流、改变雨水渗透路径、影响边坡土体的渗透性等来保护坡体。细叶结缕草护坡作用下边坡土体的含水率达到稳定状态所需时间最长,裸土边坡土体的含水率达到稳定状态所需时间最短,可见细叶结缕草对边坡土体的渗透性影响最大。
Abstract:
Slope model tests of outdoor natural and indoor artificial rainfall were conducted, the used floury soil was taken from Meilan District of Haikou City, the vegetation of the test model is bare soil, tuber fern and fine leaf zoysia. The monitoring system of the model may measure and collect real-time soil moisture content of the tested slope model. By comparing the change of moisture of the three different vegetation slope models in two indoor artificial rainfall and outdoor natural rainfall tests, results show that the vegetation protects the slope mainly by intercepting rainfall-formed surface runoff,changing the seepage path of the rainwater, affecting the permeability of the slope soil body and so on.Moisture content of fine leaf zoysia slope soil requires the longest time to reach a steady state,while moisture content of bare soil shope soil needs the shortest time to reach the steady state,so fine leaf zoysia’s effect on the slope soil’s permeability is maximum.
