特高精度水电站施工控制网分析与研究

Research on the especially high accuracy construction network of hydropower stations

本文从水电站施工控制网特高精度要求出发,结合白溪、黄坛口、泰安、桐柏和宜兴等五个具体的施工控制网,对网形、观测精度、网的精度、可靠性、费用及其相互关系等,进行了较深入的研究,并按基于观测值内部可靠性的模拟优化设计方法进行了网的模拟计算、优化设计和比较分析。

This paper discussed the relation of structure of construction network,observation accuracy,networks accuracy,re-liability and cost combined with five construction networks of hydropower stations.The net simulated calculation and opti-mizition based on inner reliability of observation are discussed in detail as well.
