摘　　要：随着国家钢铁技术的进步,拉森钢板桩异型高强度钢材以前只能由国外进口,现改为全面国产;城市的发展,排水沟槽、基坑越来越深,拉森钢板桩具有止水、支撑双重作用,是一种经济、高效、快速的支护方式。本方案对拉森钢板在桥梁基坑中的实施应用进行了详解,对施工过程如打桩、支撑、拔桩、监测等进行了详细的描述,证明方案可行,可对今后同类项目提供借鉴。With the technical progress of State iron and steel companies,profiled high-strength steel for Lassen steel sheet pile used to be imported only from abroad before,but now it is made in China.With the development of the city,drainage ditches and foundation pits are getting deeper and deeper,Larsen steel sheet pile is an economical,efficient and fast supporting method due to its dual functions of water stop and support.The practical application of Lassen steel sheet in bridge pile foundation is described,and the construction processes such as pile driving,pile pulling,supporting,monitoring are described in detail,which proves that the scheme is feasible and can be used for reference for similar projects in the future.
