| Abstract: | In order to exploit the coal under the steel tower of high-voltage transmission line and ensure the safety of the tower,we studied the safety of such tower affected by caving mining,based on the data of field observation and surface movement and deformation predicting,from the following aspects: uneven subsidence of the tower foundations,slope of the tower,torsion,space between tower foundations and subsidence velocity of the tower.The results indicate that the uneven subsidence of the tower foundations and... |
