摘要
针对井筒变形监测时,激光发散造成测量距离短的问题,本文开展了基准建立与传递、新激光点坐标计算等关键技术研究,提出了多距离交会法和平面参数转换法计算新激光点坐标,能有效减少计算量,提高激光基准监测方法的实用性,最后结合工程实例验证了该方法的精度,并对井筒进行了详细的形变分析。
In this paper,the key technologies such as the establishment and transmission of laser datum and the computation of laser point coordinates are deeply studied in response to the problem of short measuring distance caused by laser dispersion in shaft deformation monitoring.The proposal of multiple distance intersection method and plane coefficient transformation method to calculate the new laser point coordinates could effectively reduce the amount of calculation and improve the practicability of the method.Finally,the accuracy of the proposed methods is verified via an engineering case,and the deformation analysis of shaft is also carried out in detail.
