摘要
对影响吊钢丝联系三角形法定向精度的因素进行了分析,提出相应的施测方案,并通过在上海青草沙原水过江管隧道大型深竖井定向中的实际验证,论述吊钢丝联系三角形法在隧道测量大型深竖井定向中的应用价值。
According to the precision estimation of traditional Long wire-Connection triangle method, and the actual use of Long wire-Connection triangle method in Large shaft orientation of Qing Chaosha original water tunnel crossing the Yangtze River of Shanghai, the Practicability of Long wire-Connection triangle method in Large shaft orientation of tunnel is discussed.
