地铁保护区建筑物垂直度监测技术探讨

当地铁保护区内有施工项目时,需要对邻近建筑物的垂直度进行监测,通过对比多种监测方案的操作性、可靠性,指出使用高精度免棱镜全站仪极坐标法获取测点坐标,以垂直度的差值为监测指标,以向量的形式在依照建筑物平面形状建立的坐标系中予以可视化显示,能够直观地反映建筑物垂直度的变化态势。

Discussion on Verticality Monitoring of Building in Subway Protection Zone

There should be building verticality monitoring during the construction in subway protection zone,This article describes compares the interoperability and reliability of three monitoring programs,which points out that,getting the monitoring points’coordinate by high-precision prism total station can provide higher accuracy using polar coordinates observation,using the difference values of verticality as the monitoring index,displaying in the coordinate system base on the planar shape of the building with a vector form,which can get a better responsible of the verticality changing of building.
