谈换填强夯法处理不均匀软基施工技术

On construction technique of replacement and dynamic compaction method in dealing with uneven soft foundation

结合工程实例,对换填强夯法处理不均匀软基进行了研究,从区域划分、清除不良土层、回填碎石、强夯处理、不停航施工等方面实施控制,提出了换填强夯法处理软基的方法,通过机场工程实体试验论证,地基承载力达到了设计要求,工期得到了保证,为其他不均匀软基处理工程提供参考。

Combining with the engineering cases,the paper researches the replacement and dynamic compaction method in dealing with the uneven soft foundation,undertakes the control from the regional classification,clearance of unfavorable layer,refilling of gravel,dynamic compaction treatment,and non-stop construction,points out the method of the replacement and dynamic compaction in the treatment of the soft foundation,proves according to the experiment on the airport projects,and indicates the foundation loading capacity achieves the design requirements and the construction period is ensured,so as to provide some reference for the treatment of other uneven soft foundation.
