大埋深地下高铁站风压、温度研究与实践

Study and Practice of Wind Pressure and Temperature in Underground High-speed Railway Station with Large Buried Depth

八达岭长城站是京张高铁在北京市境内重要的中间站,位于延庆区八达岭风景名胜区,深埋地下102.55m,作为国内埋深最大的高铁站,其地下部分列车风压大和冬季温度低一直是建设和运营单位重点关注的两个问题。本文对该问题从设计之初研究、建设期间实践及开通运营效果全过程进行探讨,分析产生原因、详述采取措施和总结建设经验,为类似项目提供借鉴。

Badaling Great Wall Station is an important intermediate station of Beijing-Zhangjiaku high-speed railway in Beijing.It is located in Badaling Scenic Area of Yanqing District,with a depth of 102.55m.As the largest buried high-speed railway station in China,the construction and operation units always pay attention to the two problems of high wind pressure and low winter temperature of the underground part of the trains.This paper discusses the whole process of this problem from the initial research of design,the practice during construction and the operation effect,analyzes the causes of this problem,details the measures taken and summarizes the construction experience,so as to provide reference for similar projects.
