沿海淤泥土地基中新型双排PC工法桩围堰的应用分析OA
Application analysis of the new type double row PC pile cofferdam in the coastal silty soil foundation
新沂河海口枢纽北深泓闸下游围堰工程为所处河道地基含一定深度的淤泥土,为提高围堰工程效益,设计采用一种新型双排PC工法桩围堰结构形式,通过分析其结构优点,结合规范,对该围堰进行抗倾覆稳定性验算、抗水平滑移验算、抗隆起验算以及深层抗滑稳定验算,得出该围堰结构形式稳定安全的结论.对其施工方法和工艺进行优化,为沿海地区同类围堰工程推广提供价值性参考.
The foundation of the river channel in this project contains a certain depth of silty soil.In order to improve the efficiency of the cofferdam project,a new type of double row PC pile cofferdam structure is designed.By analyzing its structural advantages and combining with standards,the cofferdam is subjected to stability checks for overturning,horizontal sliding,uplift,and deep-seated anti-slide stability.The conclusion is drawn that the cofferdam structure is stable and safe.The construction method and technology are optimized to provide a valuable reference for the promotion of similar cofferdam projects in coastal areas.
