本文根据黑龙江省双鸭山发电厂二期工程对膨胀土的勘测结果,按国家标准《膨胀土地区建筑技术规范》GBJ-87(报批稿)(以下简称为《规范》)对膨胀土的一般物理性质、膨胀潜势分类等特征以及大气影响深度和大气影响急剧层深度;膨胀土地基胀缩变形量的计算和胀缩等级的划分进行了剖析。
This article is based on the results of the investigation of expansive soil in the second phase of Shuangyashan Power Plant in Heilongjiang Province and the general physical properties of expansive soil according to the national standard “Technical Specification for Expansive Soil Area” GBJ-87 (approved draft) (hereinafter referred to as “the Code”). The classification of the expansion potential and other characteristics, as well as the depth of atmospheric influence and the depth of atmospheric influence, the depth of the depth; the expansion and contraction deformation of the expansive soil and the division of the expansion and contraction level were analyzed.
