Expansive Soil Analysis and Evaluation of a Substation in Heilongjiang Province

膨胀土具有吸水膨胀、失水收缩的变形特性,常对建筑物上部结构的稳定性带来影响。黑龙江省膨胀土分布并不广泛。文章着重对变电站场地膨胀土的胀缩特性进行归纳整理及分析,确定了膨胀土的胀缩等级,并对地基评价提出了建议,为该地区类似工程积累一些经验。

Expansive soil has deformation characteristics, namely when losing water, leading to severe influence on the structures Heilongjiang Province. This paper focuses on the characteristics substation, then determines the expansive soil swelling and evaluation and recommendations. It will provide experience for it swells when absorbing water, shrinks built on it. It is widely distributed in analysis of expansive soil in the field of shrinkage grades, and the foundation the similar project.
