摘要
地铁车站修建常常受制于周边环境影响,以西安地铁五号线黄雁村站半盖挖基坑工程为背景,在对地下车站常用的施工工法做了对比和分析的基础上,确定采用半盖挖法并对施工中基坑围护结构的受力、变形和稳定进行研究,分析基坑施工对周边环境的影响,结果表明该支护方式安全可靠,具有良好的经济效益和速率。
Subway station construction is often subject to the impact of the surrounding environment,so this paper takes the half cover excavation foundation pit project of Huangyancun station of Xi’an Metro Line 5 as the background,compares and analyzes the common construction methods of underground stations,determines to adopt the half cover excavation method,studies the stress,deformation and stability of the foundation pit enclosure structure in the construction,and analyzes the impact of foundation pit construction on the surrounding environment.The results show that the support method is safe and reliable,with good economic benefits and speed.
