高层建筑的竖向双控法

The Vertical Double Control Method Of The High-rise Building

为有效地控制高层建筑的竖向测量精度,采用激光铅垂仪、光学经纬仪,用双控法对其进行竖向控制,以内控为主,外控为辅,相互校核以保证测控要求。技术经济分析表明,其测量精度高,速度快,实践效果良好。

In order to control the vertical measure accuracy of high-rise building effectively,laser plumb instrument and optical theodolite were used to control the vertical direction by means of vertical double control method.The inside control is principal, outside control is assistant,and the two kinds of measurements are checked each other to assure the request.The analysis of technical economy shows that this method is of high accuracy,high speed,and good practical effect.
