| 摘 要： | 由于海上日照辐射强,桥位处昼夜温差较大,温度环境较为复杂,同时二等水准观测存在夜间作业困难、观测效率低以及劳动强度大等问题。文中采用高精度全站仪徕卡TS30测量机器人进行精密三角高程测量代替二等水准测量,从精密三角高程测量的原理和误差改正角度进行分析,并结合港珠澳青州航道桥的工程案例进行验证。结果表明:在一定的距离和竖直角监测范围内,精密三角高程测量可以代替二等水准测量。

| Abstract: | Due to the strong sea sunshine,and that the temperature environment of bridge site is quite complex with a large diurnal temperature difference,at the same time,in order to overcome the difficulties in the night operation of the second order leveling,the observation efficiency is low and the problem of labor intensity occurs.This paper tries to replace second-class leveling with precise trigonometric leveling by high precision geo-robot Leica TS30,BY carrying on the analysis from the points of principle and error correction of precise trigonometric leveling measurement,and verifying them with the proj ect case of the Hong Kong-Zhuhai-Macao Bridge Qingzhou Channel Bridge.The results show that second order leveling can be replaced by precise trigonometric leveling within a certain monitoring range of distance and vertical angle. |
