砂土地层地基处理方法分析

Analysis of foundation treatment method in sandy soil stratum

在毛乌素沙漠地区,浅层分布着松散砂土。该地区地基承载力较低,往往无法满足建构筑承载力的要求。同时,地层压缩模量低,不均匀沉降明显,因此选取较为有效且经济合理的地基处理措施,来提高地基承载力、改善砂土的变形特征,是该地区地基处理的重点和难点。本文通过比较几种常见的砂层地基处理方法,从处理效果和经济性角度,分析和总结了此类地层较为适用的地基处理方法。

In Mu Us Sandyland,loose sand is distributed in shallow layers.The bearing capacity of foundation in this area is low,which can not meet the requirement of building bearing capacity.At the same time,the compressive modulus of formation is low and the uneven settlement is obvious.It is the key and difficult point to select effective and economic measures to improve the bearing capacity of foundation and the deformation characteristics of sand.In this paper,several foundation treatment methods are compared,and from the view of treatment effect and economy,the suitable foundation treatment methods are analyzed and summarized.
