在油罐工程中用砂井堆载预压处理软土地基

Treat Soft Foundation in Oil Storage Tank Engineering With Sand Well Stack Load Prepress Method

砂井堆载预压处理软土地基在所承建的孟加拉国某油罐工程中得到了成功的应用。地基最终沉降量采用分层总和法进行计算 ;地基固结度采用一维砂井固结理论Terzaghi修正法进行计算 ;地基强度增长采用有效应力法进行计算 ;地基稳定性采用Skempton公式极限承载力法进行验算。施工时对罐基沉降做了详细观测 ,并据此对最终沉降量做了修正 ,取得了满意的结果。

This method has successfully used on certain foreign engineering.The final subsidenec amount accounts with the divide tier sum total method,the solidity of the foundation accounts with sand well solidity theory Terzaghi revision method,and the increasing of the foundation strength accounts with the effective stress method.Detail observation has made on the subsidence of the foundation,based on it revision has made to the final subsidence amount and get safisfying result.
