北京某地铁盾构区间位于北京市老城区,施工过程中需长距离下穿老旧平瓦房,为掌握盾构下穿平瓦房过程中沉降变形规律,为后续施工提供指导,选取了其中一个区段进行试验,通过对该区域的房屋进行严密监测,获取了不同盾构参数下的沉降数据,对监测数据进行了详细分析后,总结出盾构下穿平房区域的沉降变形规律,对日后类似工程有重要的参考和借鉴价值。 A certain subway shield zone in Beijing is located in the Old City of Beijing. During the construction, the old flat-tile house needs to be worn down long distances. In order to grasp the settlement and deformation rules during the process of wearing flat-tile houses under the shield and provide guidance for subsequent construction, A section of the test, through the close monitoring of the housing in the region, obtained under different shield parameters of settlement data, a detailed analysis of the monitoring data, summed up the shield under the settlement of the bungalow settlement law, the Similar projects in the future have important reference and reference value.
