摘要
为了解决苏州河深隧工程超深竖井联系测量的难题,本文详细阐述了联系三角形法的原理及作业方法,对联系三角形进行了精度分析,推算出地下起始边方位角的精度影响公式并进行模拟计算。同时研究了影响竖井联系测量定向精度的各种有关因素,并提出相应措施。最后结合工程试验,证明了联系三角形法在超深竖井联系测量中是可靠而有效的。
To solve the problem of connection survey for Suzhou River deep tunnel project,the paper elaborates the principle and operation method of connection triangle method. Based on accuracy analysis of connection triangle,the error formula for initial azimuth of underground traverse is derived and simulated. Various relevant factors which may influence the orientation accuracy are studied and the measures are proposed. At last,it is proved that the connection triangle method is efficient and reliable for the connection survey of super-deep shaft,combined with engineering test.
