箱涵顶进施工中沉降与定位技术研究

Study on settlement and location technology in box culvert jacking construction

以太原市某下穿铁路框架桥箱涵顶进施工为例,对箱涵顶进施工中的沉降与定位问题进行深入分析,并通过布控沉降量监测网、实时定位分析、数值模拟规律等技术跟踪施工进程,确保地上既有铁路不受影响。

Taking the jacking construction of box culvert of a certain underpass rail-way frame bridge in Taiyuan as an example,the settlement and positioning problems in the jacking construction of box culvert are analyzed in depth,and the construction process is tracked through the monitoring network of settlement,real-time positioning analysis and numerical simulation la-w,so as to ensure that the existing rail-ways on the ground are not affected.
