英文摘要: The city development of the society leads to the congestion of ground traffic, which makes people build a large number of underground tunnels. Underground tunnels often encounter underground pipelines or other tunnels, and how to build safety is the most important. However, at present, the theoretical knowledge of tunnel construction is far behind engineering practice, so it is urgent to develop relevant research. The shallow excavation method is an important method to build the tunnel. During the construction, the ground disturbance is small, the ground traffic and the build-ings are not affected. The funds and equipment are relatively small, and many different sections can be excavated flexibly. Based on the excavation of the Tunnel Six in Beijing metro line, this paper uses FLAC3D...
中文摘要: 城市的快速发展导致地面交通拥挤,大量地下隧道被修建,修建过程中会遇到地下管线或者其他隧道等情况,如何安全的修建是重中之重。目前隧道修建的理论知识远远落后于工程实践,需发展隧道修建的相关研究。浅埋暗挖法是一个修建隧道的重要方法,施工过程中对地面扰动小,不影响地面交通和建筑物,需要的资金和设备相对较少,可以开挖多种不同的断面,本文基于北京地铁六号线西延段田村站~海淀五路居站区间隧道的开挖,利用FLAC3D建模,通过更换土压大小和衬砌参数来分析土压、衬砌参数等对地面沉降的影响以及浅埋暗挖法对管线的影响。
