摘要
实地测量时经常遇到测点间不通视,又无其他测点可用的情况,从测量原理、观测方案、数据平差、支导线测量等方面综合论述,运用数学知识解决利用两个不通视控制点进行导线测量放样的过程,并结合水峪煤矿九采区实例加以说明。
In field measurement,it often encountered in measuring point invisibility between measurements, and no other measuring points available.This paper comprehensively discussed the measurement principle, observation scheme, data adjustment, traverse measurement,etc. Mathematical knowledge was applied to solve the process of wire measurement lofting using two visibility control points, combined with the examples of No.9 mining area of Shuiyu Coal Mine,the detailed measures were proposed.
