摘要
从李家河水库枢纽区地形特点出发,叙述了施工控制网的方案优化设计思路、施测方法及要求。通过工程具体实例,对平面和高程网外业观测成果验算和数据平差处理后的精度统计分析,验证了优化方案的应用效果,其结果可达到同等级预期精度指标,作业效率高。
In view of the topographical features of Lijiahe reservoir project area, the paper describes the design concepts on option optimization of construction control network, surveying method and requirements. Based on actual practice of project, the application effects of optimal option is verified through check calculation of the field observation results of plane and elevation networks and accuracy statistic analysis after data adjustment, the results of it can reach the same level predicted accuracy index, and the operation efficiency is high.
