摘要:
介绍了测距三角高程测量的误差来源及减弱或者消除方法。结合不同海拔地区的4个水利水电大坝边角施工控制网和1 个变形监测网测量项目观测数据,通过对采用有强制对中装置的观测墩和使用脚架光学对中方法施测的实践工程数据的计算分析,验证了测距三角高程测量代替二等水准测量在山区应用的可行性。对在山区水利水电工程建立精密三维控制网具有一定参考价值。
Abstract:
The error sources and methods of reduction or elimination by trigonometric leveling are introduced in this paper.The observation data of four water conservancy and hydropower dam side angle construction control network and one deformation monitoring network are obtained.Through the calculation and analysis of practical engineering data by observation pier with forced centering device and measurement method using optical tripod,the feasibility of trigonometric leveling instead of two leveling in mountainous area is verified.It has certain reference value for the establishment of precise three-dimensional control network in hydraulic and hydropower projects in mountain area.
