Joint adjustment of multi-source data for planar construction control networks of pumped storage power stations
The pumped storage power stations currently under construction and planning are located in a forested area,which is limited by poor visibility conditions in the survey area and the large obstruction of satellite signals by trees when using a global positioning system(GPS)scheme to establish a planar construction control network.The establishment of their planar construction control networks is extremely difficult.In order to improve the establishment of construction control networks under extremely difficult forest conditions,this article used the GPS measurement scheme and joint adjustment scheme of multi-source data to calculate and analyze the results of the planar control network.It was proven that the joint adjustment of multi-source data could obtain qualified results of the planar control network.In the implementation process,it is necessary to focus on the compatibility of different observation methods to obtain side lengths and try to avoid large height differences between adjacent points when laying out the control network,so as to achieve better results.
