According to the characteristics of the Water Diversion Project in Central Yunnan, the application of error theory analysis and simulation calculation method, the influence value of the elevation error of the channel line on the longitudinal slope is obtained. It is deduced that the first-level elevation control network of the project should use the second-level level control network. Combined with the analysis and calculation of the error in the weakest point elevation, it is analyzed that the project should use the third-level encryption high-speed control network. Finally, through the valuation calculation, it is determined that the Water Diversion Project in Central Yunnan does not need to correct the lunisolar attraction in the elevation control network.
