多种软基处理技术在锦州港码头工程中的应用

Application of various soft foundation treatment technologies in wharf project of Jinzhou Port

传统水运工程中,吹填区域地基处理以真空预压或堆载预压工艺为主,非吹填区域地基处理以强夯工艺为主。以锦州港第二港池集装箱码头二期工程为例,根据不同地质情况将场区进行分区,通过选用不同工艺进行综合处理。根据堆载预压、强夯(强夯置换)、振冲3种处理工艺的处理结果,进一步验证3种软基处理技术的适用条件,为类似工程提供参考。

In traditional waterway engineering,the main method of foundation treatment in dredger filling area is vacuum preloading or surcharge preloading,and the main method of foundation treatment in non-dredger filling area is dynamic compaction.Taking the second phase of the container terminal project of the second harbor basin of Jinzhou Port as an example,we divide the site area according to different geological conditions,and carry out the comprehensive treatment by choosing different processes.According to the treatment results of surcharge preloading,dynamic compaction(dynamic compaction replacement)and vibroflotation,we verify the applicable conditions of three soft foundation treatment technologies,which can provide reference for similar engineering construction.
