察尔汗盐渍土工程特性与地基处理方法研究
|
摘要
为了解察尔汗盐湖盐渍土工程特性,采用钻探、原位测试、工程物探、室内试验等多种勘察手段,系统研究了盐渍土物理力学性质,现场对有害毛细水上升高度进行了实测,对地基土承载力进行了静载试验,取得了大量测试数据。在对盐渍土工程特性、土和地下水腐蚀性进行分析评价的基础上,对盐渍土地基处理方法进行比较研究,为同类工程积累了经验。
A variety of investigation methods were adopted such as drilling,in-situ test,engineering geophysical prospecting and laboratory tests in order to find out the engineering properties of saline soil of Qarham Salt Lake,and systematically study the physical and mechanical properties of saline soil,and a field actual measurement for lifting height of harmful capillary water was done,and static loading test was carried out on the bearing capacity of foundation soil to get lots of data.Due to the analysis and assessment of engineering properties of saline soil and corrosiveness of soil and groundwater,a comparative study on the foundation treatment methods of saline soil had been carried out,which can provide reference for similar engineering construction.
