摘要
某超高层工程位于季风气候区域,全年90～140d为6级以上大风天气.通过利用激光垂准仪作轴线控制点基本投点,再利用GPS方法进行点位测量及检核修正,同时GPS还对施工环境包括强风等对钢结构产生的形变进行分析.试验数据显示,该方法在实践中切实可行.
A superhigh building project is located in a monsoon climate region, where suffers strong wind above scale 6 for 90 to 140 days per annum. Laser plummet is used for axial control point projection and then GPS method is used for point position measurement and correction. Meanwhile, GPS could also analyze the deformation of steel structure caused by the construction environmental conditions, including strong wind, etc. The test results indicate that this method is feasible in practical projects.
