Stability evaluation of transmission tower above the goaf by fuzzy comprehensive evaluation method and analytic hierarchy process

Abstract

Combination of the load-bearing conditions, the tower shape and service time, and the geological and basic conditions of the service environment of the tower, various factors that influence the stability of the towering tower near goaf were classified by using fuzzy comprehensive evaluation method and AHP, and the influence factor model was established. The impact factors were evaluated from low to high, the influence of the geological and basic conditions of the service environment is maximal, and determined the approximate rock roadway is stable and no measures need to take to improve the stability of the tower.
