Research on Pile Foundation of Transmission Tower Stability Analysis Based on Numerical Simulation in Karst Areas

Abstract:

The stability of the karst area transmission towers pile foundation and engineering deal with the problem, the success or failure related to the electric power system operation, the karst area transmission towers pile foundation stability of the subject, the power sector is currently no in-depth case studies, qualitative analysis has been used method and semi-quantitative analysis of the reliability of the method of evaluation results is restricted, and thus how to seek a more rational analysis method and its application in theory worthy of further exploration. In this paper, numerical simulation conducted in-depth study and exploration of a karst area transmission tower pile stability evaluation, design, construction and operation of the project has a certain reference value, has certain reference significance for similar construction projects.
