Numerical Simulation Analysis of Loess Slope Stability under the action of Power Tower foundations

Electric energy is the national key energy, and the safety construction of power tower is very important. In this paper, the influence of power tower foundation layout on slope stability in loess slope area is studied. Qingyangning County, Gansu Province is selected as the target area. Based on climate and rainfall data, numerical simulation method is adopted. Firstly, the study area is determined and the data are collected. Then, AUTO CAD and FLAC3 D are used to simulate the slope stability under different rainfall conditions and analyze the influence of rainfall. Then, several tower foundation layout schemes are determined, focusing on the influence of tower foundation on slope settlement under heavy rainstorm conditions, and calculating the slope safety factor and settlement of different schemes. Finally, the optimal tower foundation layout scheme is obtained, which provides reference for designers. This study is of great significance to the safety construction of power tower and the improvement of loess slope stability.
