Chinese Abstract

浅埋暗挖法在地铁建设中应用日益广泛,大断面隧道亦愈来愈多,大断面双连拱隧道开挖引起地层变形大,施工难度大.本文以西安地铁四号线飞天路~航天大道站区间四线双连拱隧道为背景,采用现场监控量测手段,对隧道开挖引起的地表沉降及管线变形变化特征进行分析.对类似工程的设计施工具有一定的参考价值.

English Abstract

Shallow buried and excavated method is widely used in subway construction, and large-scale tunnels are increasing. Large-scale double-arch tunnel excavation causes large strata deformation and construction is difficult. In this paper, the surface subsidence and the deformation characteristics of the pipeline caused by the tunnel excavation are analyzed by means of field monitoring and measurement in the background of the four-track double-arch tunnel between Feitian Road and Hangtian Road of Xi'an Metro Line 4. It has certain reference value for the design and construction of similar projects.
