摘要
结合福建西气东输九龙江小直径深竖井长隧道工程施工测量控制技术,介绍了高精度磁悬浮陀螺全站仪新技术,垂准仪+弯管目镜+全站仪联测技术方法,常规垂球悬吊+全站仪引测技术,顺利将地面坐标控制系统垂直引入至小直径深竖井底部及长隧道内部,圆满实现了长隧道对向开挖施工的高精度贯通目标。通过3种方法的实施应用对比,验证了前2种新方法优于常规方法。
Abstract
Based on engineering practice, this paper introduced some new measurement methods in tunnel construction. These methods can satisfy the requirement of high precision of long tunnel. Based on comparison of the three methods, new methods were better than the common methods.
