摘要
凤凰国际传媒中心建筑外墙由9段不同直径、不同圆心的圆弧组成,圆弧墙体的定位成为本工程测量工作的重点与难点。利用AutoCAD和全站仪建立平面、高程施工测量控制网,测量出控制点、弧度、距离,使用弦线支距法确定圆弧墙体的位置。为了减小误差,达到精度要求,所有的弧形轴线加密到500mm一道。该方法可提高建筑施工测量的精度,缩短施工工期从而增加经济效益。
The outer building wall of Beijing Phoenix International Media Center consists of nine different diameter and circle center,so location for arc wall is the difficulty for engineering measurement.By using AutoCAD and total station,the plan and elevation measuring control nets are built up to measure control points,radian and distance,and chord offset method is applied to assure the position of arc wall.In order to decrease error and meet the precision requirement,all the arc axes are densified to 500mm.This method can improve measuring precision,save construction period and increase economic benefit.
