计算机辅助测量定位在斜拉桥索导管施工中的应用

Applicatioin of Computer's Aided Measurement Positioning in Construction of Cable Duct of Cable Stayed Bridge

以大连金州滨海大桥为例,简要介绍斜拉桥中计算机辅助测量定位索导管技术,主要是通过计算机AutoCAD绘制主塔索导管三维图,通过全站仪对索导管实际坐标的测量,将实际坐标输入计算机中,与设计坐标进行对比。找出偏差量,再进行调整索导管,使其达到设计要求。

As example with Binhai Bridge in Jinzhou of Dalian,the paper shortly introduces the techniques for computer＇s aided measuring positioning of cable duct. It inputs actual coordinate into computer,and compares it to design coordinate through AutoCAD of computer draws three dimentional diagram of main tower cable duct, again by means of the Globel Positioning System（GPS） measures the actual coordinate of cable duct. Then the deviation value is solved for. The cable duct is any more adjusted to attain the requirements for design.
