Abstract: Due to the limitation of the passage space and the topography, some towers of the power transmission line need to be installed on the slope. With the gradual loading of tower construction, the slope stability will become worse and worse if the slope is not reinforced in time, which will induce a potential safety hazard to the tower and even cause the tower collapse. In addition, the slope remediation is always time consuming. which will greatly affect the timely completion of the power transmission construction project. Based on the Lizheng geotechnical engineering evaluation and analysis software, the staged remediation of the high and steep slope of the tower of a power transmission line has been analyzed by the limit equilibrium method. The analysis results show that selecting reasonable staged remediation method can achieve these goals, such as reasonable arrangement of the power transmission engineering process, saving power transmission construction time and moving the project forward smoothly.
