关于建立区域施工平面控制网几个问题的探讨

Discussion on several issues of establishing regional construction plane control

文中就施工平面控制网的等级确定 ,以及如何选择合适的高程抵偿面使投影变形值最小 ,进行细致的分析与探讨 ,总结出各类工程建筑限差与拟建网的精度配比关系 ,推证出最佳抵偿高程面之高程 ,对于工程建网具有一定的指导意义。

This paper gives a detailed analysis and discussion on how to define the grade of construction plane control network and how to choose appropriate compensating surface to get a smallest projecting deformation, sums up proportion relation between limited error of certain building and accuracy of establishing control network, and deduces the level of optimistic compensating surface. The analysis and discussion are meaningful to some extent in guiding the installation of engineering control network.
