以新加坡填海区公铁两用复合高架桥为例，介绍了钢板桩在承台开挖支护工程中的应用技术，叙述了基于 PLAXIS 软件的摩尔-库伦模块的钢板桩的长度、支撑和围檩结构验算以及施工过程中钢板桩、围檩、支撑的安装、拆除要点等方面。通过本工程实际应用证明，钢板桩支护既能满足施工的安全要求，同时能保护环境和节约投资，具有优越的工程性能。
以新加坡填海區公鐵兩用複閤高架橋為例，介紹瞭鋼闆樁在承檯開挖支護工程中的應用技術，敘述瞭基于 PLAXIS 軟件的摩爾-庫倫模塊的鋼闆樁的長度、支撐和圍檁結構驗算以及施工過程中鋼闆樁、圍檁、支撐的安裝、拆除要點等方麵。通過本工程實際應用證明，鋼闆樁支護既能滿足施工的安全要求，同時能保護環境和節約投資，具有優越的工程性能。

Based on the combined rail-cum-road viaduct project in Singapore Reclamation,this paper introduces the application of steel sheet pile during the excavating and supporting process of pile cap and the effective length of the steel sheet pile.The checking of supporting and circuit purlin struc-tures,erection of steel sheet pile and circuit purlin and demolishing points are introduced in detail. The practical application of this project shows that the support technology of sheet pile has superior engineering properties which can not only satisfy the safety requirements of construction but also en-sure environmental protection and conservation.
