大型建筑群施工测量技术

The Construcable Metrical Technology of Large-Scale Building Group

福建省博物馆是由多个单位工程组成的大型建筑群 ,其基本特征是超长超宽 ,建筑物平面定位关键是保证建筑物平面轴线定位的准确性 ,同时测量精度必须符合工程测量规范要求。为此 ,采取建筑场区控制网和建筑物平面轴线控制网的测控措施 ,建立校正偏差计算控制系统并辅助多种测量技术方法 ,保证了大型建筑群施工测量导线精度要求≤ 1/ 5 0 0 0允许偏差范围内。

The museum of the FuJian province is a large scale building group constituting from many projects.Length and width is its basic characteristic.The fixed position of the building plane mainly guarantee the metrical accuracy must be fit for the code for engineering surveying .For this,we adopted various metrical measures such as the building field controllable net and plane axis controllable net,established deviation corrected computation and controllable system,and depend on various metrical technological means.These guarantee the large scale building group's construable metrical accuracy whose range of admissible deviation is less than and equal to 1/5000.
