摘要
结合长沙某地铁站施工监测工程实际,利用建筑物墙角等特征点作为基准点,观测目标.通过坐标系转换,建立垂直于基坑方向的监测坐标系.利用误差传播定律,确定其观测精度及其在工程实际中的可行性.
Taking a complicated foundation pit in Lanzhou as the background,the build- ing corner feature point is used as the reference point target, and the coordination at the direction of perpendicular to the foundation pit sideline is established. The observation accuracy and feasibility of the new formula was testified by error spread law.
