山西省坪上应急引水工程供水管道软基础工程特性分析

Analyzing the Features of Soft Foundation Works of Water Supply Pipe in Shanxi Pingshang Emergency Water Diversion Project

以坪上应急引水工程管道沿线的高地下水位软基为对象,对其容重、天然含水率、塑限、液限、孔隙比、渗透系数、压缩系数、抗剪强度等物理指标进行了分析研究,掌握了高地下水位软基条件下的特征,为高地下水位软基础的处理提供依据,也为该地区的水利建设和公路建设提供了参考依据。

Taking the soft soil foundation with high groundwater level along the pipe line of Pingshang Emergency Water Diversion Project as an object,this project＇s some soil physical indexes such as soil bulk density,natural mois-ture content,plastic limit,liguid limit,void ratio,coefficient of permeability,contraction coefficient and resistance to shear are analyzed,and this foundation＇s features are known well.All of these results provide the basis to treat the soft soil foundation,and provide the reference to hydraulic and highway construction in this area.
