拉森钢板桩在入江口翻板闸深基坑支护工程中的应用

Lassen Steel Sheet Pile's Application on Deep Foundation Pit Supporting Engineering in Estuary's Flap Gate

通过对具有较深淤泥层的10.3 m的入江口翻板闸深基坑支护工程实例的设计、施工分析,提出了采用拉森钢板桩为支护结构,内设两道钢支撑的设计方法,对比其他深基坑支护形式具有很好的经济效益,从而为深基坑的支护设计提供参考借鉴。

By analyzing the design and construction of deep foundation pit’s support as well as dewatering project with 10.3 m deeper slit layer used as the the estuary’s flap gate,the paper put forward the lassen steel sheet pile as the support-ing structure,with two steel supports and design methods.It had a very good economic benefit in contrast to other deep foundation pit’s support,thus it could provide references for deep foundation pit’s support design.
