水电工程施工控制网精度指标分析

Design and Analysis of Accuracy Index of Construction Control Network Based on Hydropower Project

本文从建立水电工程施工控制网的主要作用出发,通过控制点起始误差对工程建筑物放样点产生影响的系统分析,阐述了确定施工控制网精度指标的基本原则,对"规范"相应技术条文要求做出解释性说明,并提出在不同工程条件下施工控制网精度指标选择的设计思路,为做好水电工程施工控制网的技术设计工作具有指导意义。

This paper starts from the main role of the construction control network of hydropower project,and the basic principle of determining the precision index of the construction control network is described by the systematic analysis of engineering building influence of the control point start error. And then put forward the explanatory explanation of the corresponding technical provisions of the 'specification', and put forward the design idea of the selection index of the construction control network under different engineering conditions, which is instructive to do the technical design work of the construction control network of the hydropower project.
