大型水利枢纽工程高精度平面控制网设计研究——以向家坝为例

Design of High Precision Horizontal Control Network for Large-scale Hydropower Project:A Case Study for Xiangjiaba Dam

以向家坝和其他一些大型水利枢纽工程高精度平面控制网的设计为例,通过分析与计算,认为采用地面边角网布设方案的现状应该改变.提出以GPS网为主、精密测量地面边为辅的联合网方案.同时指出单纯的GPS网和只测少量地面边作检核的做法也不可取.以向家坝施工平面控制网为例,从精度、可靠性、点位坐标以及经费等方面对其地面网、GPS网和联合网三种方案进行详细的讨论.结论对用联合网取代地面边角网的进一步研究和制订相应规范都具有重要的理论与实际意义.
