公路路基施工放样方法

Highway roadbed construction lofting method

公路工程施工放样的主要任务是利用现代测量技术(全站仪或GPS)将设计图纸上的工程构造物的平面位置和高程在实地精确地标定出来,作为施工的前提和依据。在施工过程中,检测工程构造物的几何尺寸,以实现从设计图纸到工程实物的数据模型转换。

The main task of the highway construction lofting is using modern measurement techniques（total station or GPS） actually identify position and height of the engineering structures on design drawings in the field,as the premise and basis of the construction.Detect the engineering structure geometry during construction,to achieve the data model transformation of design drawings to the project.
