摘要

在干旱风沙区修建水土保持治沟骨干工程

可同时起到拦泥与蓄水的作用

并对改善风沙区生态环境、发展绿洲农业起到促进作用。用沟道内洪水冲积形成的砾砂混合料作为筑坝材料

既可以就地取材

又可以充分发挥土料透水性强的优势达到雨洪转化的目的。通过野外和室内试验获得的数据和资料

应用多种方法对宁夏同心县长沙河流域的上流水骨干工程的坝坡稳定性和渗透稳定性进行了分析

结果表明

干旱风沙区砾砂混合料用于修建水土保持治沟骨干工程能满足坝坡稳定和渗透稳定的要求。

Abstract

In the dry aeolian sand region

check dam s for soil and water conservation can store water and mud

improve the natural environment and enable oasis agriculture.Using a gravel-sand m ixture from channel bottom s as a building material for check dams allows use of readily available material and may also facilitate use of flood water. Follow ing a series of experimentswork

the stability of the sides and seepage flow of Shangliushui check dam were analyzed. The results indicate that gravel-sand mix can fulfil the goals of dam stability and controlled seepage flow in the dry aeolian sand region.
