大桥施工平面控制网的设计与施测

Designing and Surveying of Horizontal Control Network for Bridge Construction

对大型斜拉桥施工控制网的网形优化、精度设计、选点原则、施测方法等进行分析 ,提出使用的施工控制网网形和施测方案 ,以保证全桥及主桥与线路连接的整体性 ,同时满足定位测量、施工放样的需要。

The authors analyze the improvement in the form of controlled network,precision design,the principle of select point which control the elevation,the measurement of construction surveying that specially uesd in the cable-stayed bridge. On the basis of this ,the authors introduce the form of construction controlled network and schema of construction to the integration which the whole bridge and main bridge connected with the highway ,to fulfill the request of surveying and putting design into practise through the whole construction.
