高层建筑施工控制网方案与精度控制

High Rise Building Construction Control Network Plan and Precision Control

为了解决高层建筑施工中的难以保证垂直度、几何形状、截面尺寸尤其是垂直度控制等问题,本文以某高层建筑的施工控制网设计为例,在给出施工方案的基础上,提出了提高控制网精度的方法,确保控制网精度达到了工程精度要求。

To better solve the problems of small measurement space, poor observation conditions, unable to determine direction of the footage, long traverse survey error and leveling surveying error in large-scale footage, it takes an example in a city of the breakthrough survey, which based on the footage measurement plans. It takes the method and safeguard measures for improving the accuracy of the penetration measurement which are proposed.
