摘要
城市地铁车站施工受周边环境制约较多,选择合理的施工方法可减小施工与环境的矛盾。以某软土地区地铁车站为工程实例,通过对比分析各施工方法的优缺点,详细阐述半盖挖法在城市地铁车站施工中的应用,并从设计、导行、施工三方面对半盖挖法进行详细说明。最后,结合监测数据对施工效果进行分析,通过分析不同施工工序下地表沉降及围护结构的变形,在合理路桥体系下,半盖挖法不仅可以有效解决工期紧、交通疏导难等问题,并可取得良好施工效果。
Metro excavation is restricted by the surrounding environment at a large extent, hence a reasonable construction method which can decrease the contradiction between construction and environment should be selected. Through the com- parison of different construction methods used in excavation, the application of semi - covered excavation method in metro excavation was introduced in detail at the aspect of design, traffic organization and construction. At last, by studying the monitoring data of the surface subsidence and the deformation of the supporting structure based on various construction pro- cedures, it is concluded that with the reasonable road-bridge system, adopting semi-covered excavation method can not only solve the problems of tight schedule and complicated traffic organization, but also obtain a good construction effect.
