某桥梁独立施工控制网高程复测技术研究

Research on a Bridge Independent Construction Control Network Height Retest Technology

建立独立施工控制网是桥梁施工和安全运营的保证,而控制网的定期复测也很重要。本文以某大桥为例,就桥梁独立施工控制网高程部分的复测方法、数据平差方法、水准点稳定性探查等关键技术给予详细介绍。

Setting an independent surveying network is to ensure the safety construction and operations of a bridge. Generally,retesting control network periodically is also very important to a bridge.This paper takes a bridge as an example,expounding the key technologies on methods of reiteration,date adjustment and bench mark stability analysis in elevation part of independent construction control network in bridge construction.
