摘要
北京首都国际机场新航站楼T3B工程施工场区大,建筑物外形构成比较复杂,有多条曲线;红线桩或控制点距离较远,不易在三站内引测到建筑物附近;要求与2km外的在施工程保持轴线一致;多家土建、专业施工单位同时施工。引入导线测量的理论,对超长控制网进行导线平差,使测量误差控制在土建施工规范允许范围之内。
Terminal T3B Project at Beijing Capital International Airport has a large construction site and complicated architectural shape with many curves. Due to the far distance of the boundary piles or control points, it is difficult to lead them to near the building by three-point survey. It is required that the axes of the building under construction 2 km apart should be kept in a line. Moreover, several contractors are undertaking construction on the site at the same time. Lead survey theory was introduced to adjust the differences of control net of super long distance, controlling the survey differences to within the allowance range of the specification for civil construction.
