摘要
在国内大型成品油库工程建设中,首次全部采用强夯置换法进行回填土地基加固处理,选定试验区进行强夯置换工艺施工,并对试验施工的过程存在的问题、过程监测数据和场地检测结果等进行分析总结,对原设计施工工艺及参数进行优化调整用以指导大面积施工。最终对地基加固处理场地的工后检测以及罐体充水预压试验和建筑物使用时沉降观测的数据进行分析,总结强夯置换工艺加固处理效果,验证采用强夯置换法进行回填土地基加固处理是行之有效的,为国内后续类似工程项目及场地的地基处理工艺选择提供了新的借鉴。
In the construction of large petroleum product storage tank farm project,the dynamic compaction and replacement method was used in the improvement of high fill soils for the first time.To validate the design parameters,a trial test area was selected for application of the dynamic compaction and replacement method.The construction procedures,test results,construction monitoring data and the site quality assurance testing data before and after the improvement were evaluated for the optimization of the design parameters for the soil improvement procedures to be applied in larger areas.The post construction settlement observation data for the petroleum product storage tank water filling test as well as in the operation of the storage tanks were also presented in the paper.The results indicated the dynamic compaction and replacement method is suitable for the improvement of high fill soils.
