Geotechnical Stability Analysis of a Mast Site under Geological Hazard

As the support carrier of transmission lines, transmission towers are of great importance to the safe operation of the power grid. Geological changes and disasters often lead to the displacement of transmission towers, which eventually cause them to tilt or even collapse and fail, seriously threatening grid security. In order to accurately evaluate the stability of the mast and ensure the safe operation of the power grid, this paper investigates the historical occurrence of disasters at the site and the distribution of hazardous areas in China, and simulates the influence of geological changes on the transmission mast to obtain the weight of the influence of geological disasters on the stability of the transmission mast, which provides a reliable standard for evaluating the stability of the mast.
