Research on Construction Control Network Technology of Hydropower Project in Steep Mountainous Area
Abstract
Due to the limitation of natural geographical conditions, many hydropower hub projects are built in steep mountainous areas, which leads to difficulties in fabric control network, excessive deformation of side length projection length, long error transmission route, and low precision of control network. The accuracy of the entire control network is difficult to control. This paper discusses the establishment of a planar control network using a high-precision dual-frequency GPS receiver instrument. The elevation control network is built using precision leveling plus triangular elevation measurements. It is proved by examples that the control network established by this method can not only ensure the overall accuracy and overall consistency of the control network, but also achieve economic, rapid and efficient effects.
