钢格构柱便桥在宁波站软土深基坑开挖中的应用
The Application of Steel Lattice Column Bridge in the Excavation of Ningbo Railway Station Deep Foundation Pit in Soft Soil
摘要
Abstract
The deep foundation pit passing under the existing railway station below is often a control project in the reconstruction of the existing large railway passenger station.Combining the features and the time schedule of the Ningbo railway station and the subway foundation pit reconstruction project,this paper proposes a design scheme that a railway temporary bridge with steel lattice column crosses over the deep foundation pit in the soft soil and discusses the technical scheme of the temporary bridge.This kind of temporary bridge is a new railway bridge structure in the field of railway engineering construction in China and has played an important role in shortening construction period,ensuring safety and quality,and saving investment.It also provides references and basic application for design of deep foundation pit intercrossing with railway line.关键词
