南水北调中线渠段工程地基土的研究

Investigation of the Subsoil under Canal Sections of the S-N Diversion Central Route Project in China

简介南水北调中线工程的基本情况,通过多年的勘察和研究现已基本查明了南水北调中线工程地质条件,本文对渠段地基土的主要工程地质问题进行了专门的研究。特别是对特殊土地基、饱和砂土震动液化问题、采空区地面变形和不均匀沉降以及渠道地基渗漏等问题进行了分析,并提出了防治对策及建议。

The engineering geological condition of the whole central route of the project was investigated. In this paper the main problems about the geological properties of the canal sections of the project, especially the specified subsoil, the liquefaction of saturated sand, the ground surface subsidence over mined-out area, the seepage condition are studied, proposal are also presented.
