深厚软土河床上大型钢板桩围堰设计与探讨

Large Steel Cofferdam Pile in Deep Soft Soil of the River

中山东河水利枢纽工程修建在深厚淤泥质软土上,钢板桩围堰对于该种特殊地质条件有其独特的优越性。对此简析钢板桩围堰的设计、施工和监测情况,通过监测所得结果进行设计优化,并指导后续施工的进行。该工程表明监测工作是保证工程安全、判断险情和优化设计的关键。

Donghe Multipurpose Dam Project in Zhongshan was built in the deep soft clay.The steel sheet pile cofferdam for this kind of special geological conditions has its own unique advantages.This article describes the design,construction and monitoring.of steel sheet pile cofferdam.Through the monitoring results,which guide the design optimization of subsequent construction,this project shows that monitoring is the key to the safety of engineering,judgment of the dangerous conditions and the optimization design.
