钢板桩在铁路桥梁深基坑支护中的应用

通过杭甬客专某水中墩深基坑工程的设计与施工,介绍了钢板桩在深基坑支护工程中的应用,从钢板桩的长度计算、支撑和围檩的结构检算以及钢板桩、围檩、支撑的安装要点等方面进行了系统的叙述,通过实践证明,板桩式基坑支护具有良好的工程性能和可重复利用的特性,在满足支护结构强度、刚度要求的同时还具有较好的经济效益,是一种较为合理的支护形式。

On application of steel sheet pile in deep foundation pit support at railway bridges

According to the design and construction at some water pier pile’s deep foundation pit project along Hangzhou-Ningbo Passenger Special Line,the study introduces the application of steel sheet pile in deep foundation pit support at railway bridges,has the systematic indication from the length calculation of the steel sheet pile,the structural recalculation of the support and the circuit perlin,and the installation points for the support,and proves by the practice that the sheet pile foundation pit support has better engineering performance has the renewable feature,so it can meet the strength and stiffness’ requirements of the support structure and has better economic benefits,and it is a more reasonable support form.
