地下车辆基地带开发工程结构设计问题及对策

Study on Structural Design of Properties above Underground Vehicle Station

车辆基地置于地下可降低地下线进出场段爬坡引起的能耗,淡化对城市景观、交通引起的割裂,消化盖上物业与周边的竖向落差,提高土地集约利用度、提升土地价值,目前国内正在逐步尝试此类项目的建设。不同于以往车辆地基开发工程,此类项目结构设计还要兼顾轨道基础、基坑支护、管线等内容,目前国内尚无系统研究总结。本文结合一实际工程从结构设计角度对其前期方案定制、细化设计、工程实施等方面进行探讨,提出设计中需重点研究的内容及应对策略,为后续工程提供借鉴。

Placing the vehicle station underground can reduce the energy consumption caused by entering and leaving the station,fade the separation of the urban landscape and traffic,cover the vertical gap between the upper property and surrounding areas,improve the land utilization,and enhance land value.At present,the construction of such projects is gradually being carried out in China.Different from previous projects,the structural design of such projects should also consider the track foundation,foundation pit excavation support,pipeline etc.But there is no systematic study yet.This paper discusses the preliminary scheme,detailed design and project implementation of an actual project from the perspective of the structural design.Key research contents and preventive solutions are proposed.This study provides references for similar future projects.
