Ltd.of Hu'nan Changsha Hu'nan 410002 China) Abstract:By analyzing to the reasons that caused the insufficient bearing capacity of the foundation in the Xiang Electricity Heavy Equipment assembly workshop this paper develop a method to strengthen the weak foundation by forming posite foundations using cement-silicate grouting and mixing pile. Considering the real situation of the project this paper introduces the key points of the design construction technology.Test to the performance of the reinforcement shows that the posite foundation's bearing capacity can meet the design requirement and the effect of reinforeement is outstanding. Key words:foundation treatment;cement-silicate grouting;mixing pile;posite foundation; foundation reinforcement;bearing capacity 随着我国工程活动的日益频繁，在工程中面临布不均匀，杂填土分布范围广，埋深从 的地基处理问题也越来越复杂.地基土的分层性、7.0m不等；③杂填土种类多，有炉渣、...
