Simulation Study of Stability of the Transmission Tower Foundations on Mined-Out Area

Abstract:

As more and more electric transmission lines have to go through the mining area, if we can fully realize the collapse and deformation characteristics of mined-out area, and master the scientific laws of its occurrence and development, we may take reasonable measures to avoid the happening of accidents, ensure the line to run in a reliable way, and greatly improve the construction quality and economic benefits. For different location conditions of coal mine worked out section to the surface of the power transmission tower, we use finite difference software FLAC3D to analyze mutual influence and interaction between underground worked out section and surface iron tower foundation. The conclusion in this paper can be used as a reference to mining site. The influence range can be estimated before mining, as far as possible avoiding influence within the scope of strata. It is the key to ensure the safety of power transmission tower, people life and property.
