摘要
船闸底板深基坑开挖一般先要进行降水形成干地后进行闸室开挖施工。通过对运盐河船闸软土夹杂粉土等特殊地基的分析,结合实际开挖情况,避开了设计要求的传统降水施工方法,通过对闸室土方进行局部试开挖技术研究、分析,总结出直接对闸室深基坑土方进行开挖、局部渗水区设置反滤层和利用开挖过水通道进行地基处理的施工新技术。
The lock＇s foundation pit is usually excavated in dry condition formed by dewatering. Based on the analysis of the special foundation Yunyan fiver lock which consists of soft soil and silty soil, and combining with the actual excavation, we research a new method to avoid the traditional dewatering method. According to the research on the local trial-excavation technology for the chamber soil, we sum up a new construction technology that can directly excavate the chamber＇ s deep foundation pit, set the inverted filter locally and utilize water channel in the permeable area.
