摘　　要：大伙房输水管线海城段施工区为下辽河冲积平原,管基上部为粉砂、细砂,呈松散状态,地下水位较高,地基土存在砂土震动液化为题,为了解决该问题,采用了碎石振冲桩对该段进行地基处理,通过检测总结处理效果,为处理同类工程的地震液化地层提供一些借鉴。The construction area in Haicheng section along the Dahuofang water conveyance pipeline is located in the lower Liaohe river alluvial plain,the topside of pipe foundation is composed of silt sand and fine sand in loose state and is high of the groundwater level,there exists problem about sand vibrating liquefaction on the foundation. In order to solve this problem,the vibrating piles of debris were adopted to treat the foundation of this section,by checking the results treated,providing some reference for similar projects with layers liquidized by earthquake.
