摘要
220 kV草坝变电站场地内广泛分布的第三系砂质泥岩和泥岩具有膨胀性。本文首先探讨了泥质岩膨胀性的划分标准;其次,通过对试验结果的分析、研究,初步判定了工程区段泥质膨胀岩的工程特性;最后,探讨了泥质膨胀岩地基处理的工程对策。
The sites of CaoBa substation widely distributed within the Tertiary mudstone and sandy mudstone with expansion.Firstly,the paper discusses the division of standards;Secondly,to preliminary determine the section of the expansion of the engineering properties of rocks by analysis of test results;Finally,the expansion of argillaceous rocks of the foundation to deal with engineering countermeasures.
