Method for measuring relative displacement of power transmission tower foundation after foundation deformation
The invention discloses a method for measuring the relative displacement of a power transmission tower foundation after foundation deformation, and the method comprises the following steps: S1, defining a calculation point, and building a local coordinate system; s2, calculating the coordinate value of each calculation point after the foundation displacement occurs; s3, calculating a relative displacement value of the iron tower foundation; according to the method, the local coordinate system is established, and the displacement value is calculated by using the clear calculation point, so that errors caused by the fact that the center of the top surface of the foundation cannot be directly observed and the foundation initial coordinate actual measurement data is lacked can be effectively overcome, and more accurate relative displacement data after foundation deformation can be provided; and the requirement of iron tower structure secondary internal force analysis calculation is met.
本发明公开了一种输电铁塔基础在地基变形发生后相对位移的测量方法，包括以下步骤：S1定义计算点，建立局部坐标系；S2计算基础位移发生后各计算点的坐标值；S3计算铁塔基础的相对位移值；本发明通过建立局部坐标系并利用明确的计算点进行位移值的计算，能够有效克服因基础顶面中心不可直接观测和缺乏基础初始坐标实测数据导致的误差，从而提供地基变形后更准确的相对位移数据，满足铁塔结构次内力分析计算的要求。
