摘要
研究目的:在武汉地铁二号线循礼门车站施工过程中,通过监测数据分析与施工方案优化,使相邻轻轨桥墩的沉降趋于稳定后,有必要进一步研究桥墩的绝对沉降与差异沉降能否满足轻轨的运营要求,从而使新建地下结构的施工与已建地上结构的运营能一定程度上协同,满足各自的需求。研究结论:通过对轻轨桥墩在相邻基坑施工下的数值计算,监测数据分析,比照相关规范的要求,认为相邻轻轨桥墩的现有沉降,能达到轻轨运营的要求。
Research purposes： The settlement of the light rail bridge around the Xunlimen Station of Line 2 of Wuhan metro was considered to be stabilized after the analyzing the monitored data and optimizing the construction plan.However,it was necessary to further study whether the absolute settlement and differential settlement of the bridge pier could meet the operational requirement of light rail or not to make sure the coordination of newly-built underground structure with the operation of the ground structure for meeting the service requirements for them.Research conclusions：From the calculation of the numerical values of the light rail bridge pier,analysis of the monitored data settlement and comparison with the corresponding codes it is concluded the existing settlement of the light rail bridge can meet the service requirement of light rail.
