| 摘 要： | 基于实际工程管沟漏水的情况,考虑黄土地基土体初始含水量、孔隙比、管沟内积水压力等因素影响,给出了二维非饱和黄土地基管沟入渗的有限元计算模型,确定了模型参数,并编制软件对管沟渗水下的黄土地基水分场进行了计算分析.结果表明,土体孔隙比越大,初始含水量越大,入渗速度越快,地基增湿区域越大,但随着增湿区域的增大,入渗水量扩散作...

| Abstract: | On the basis of actual pipe leakage,considering the factors as initial loess soil water content,void ratio,water pressure in pipe,a numerical model of moisture migration in unsaturated loess foundation is given.The pressure of water in pipe trench is considered in two cases,with or without pressure respectively.The results showed that the greater the soil void ratio and the greater the initial moisture content,the faster the infiltration,the greater the humidifying region of foundation would be,but with the... |
