孔内深层强夯法处理大厚度湿陷性黄土在某变电站工程中的应用研究
摘要:我国湿陷性黄土分布范围广,湿陷性土层厚度从几米至几十米不等,根据工程特点所采取的传统的地基处理方法有垫层法、强夯法、挤密法、注浆法等,传统的地基处理方法无法做到既满足大厚度的处理要求,又满足高承载力的要求,而孔内深层强夯法能同时达到上述要求。对一处在自重湿陷性黄土场地上的某750 kV变电站工程地基处理所采用的孔内深层强夯法复合地基的设计、施工、处理效果进行了全面检测分析,并提出相关建议。
Abstract:China's loess wide distribution, collapsible soil thickness from a few meters to dozens of meters, according to the characteristics of the traditional engineering foundation treatment methods adopted by cushion method, dynamic consolidation method, compaction method, grouting method, foundation method can deal with the traditional treatment and can meet the thickness requirements. And meet the requirements of bearing capacity, while the deep hole dynamic compaction method can also meet the above requirements. The author of a design, gravity wet deep strong in a 750 kV substation engineering foundation treatment of loess site by the consolidation of the composite foundation construction and treatment effect test study to conduct a comprehensive analysis, and put forward relevant proposals.
