帽型H型钢组合钢板桩在软土基坑中的应用

Application of H+Hat combined steel sheet pile in soft soil foundation pit

本文介绍了帽型H型钢组合钢板桩在杭州软土基坑工程首次应用中的设计、施工和监测情况,主要内容涉及围护体系设计、施工及监测要求等。监测数据表明,土体水平位移值和沉降值未超过报警值,可见该围护型式的设计和施工是成功的,可为类似工程作借鉴之用。

This paper introduces the design,construction and monitoring of H+Hat combined steel sheet piles for the first time in Hangzhou soft soil foundation pit engineering.The main content involves the design,construction and monitoring requirements of the retaining system.The measured data showed that the horizontal displacement and settlement of the soil did not exceed the alarm value.It can be seen that the new type of retaining structure is successfully designed and constructed and can further be used as a reference for similar projects.
