Problems solved by technology

[0003] The stability of the foundation in the area affected by coal mining is crucial to the selection of UHV tower foundations and the laying of transmission lines. Therefore, it is necessary to evaluate the stability of the foundation in the area affected by coal mining and determine the tower erection plan accordingly. At present, there is no systematic foundation stability assessment method for the large-area coal mine mining impact area of ​​the UHV line

Abstract

The embodiment of the invention discloses a method for evaluating the stability of the foundation of a mining infection zone. The method comprises the following steps: selecting a line route direction and a tower position of a transmission circuit passing the mining infection zone; determining motion deformation parameters of ground surface of the mining infection zone close to the tower position and in a preset width range of the line route by the acquired rock parameter of the mining infection zone and mining influence parameters; and obtaining the result of evaluating the stability of the foundation according to the motion deformation parameters. According to the embodiment of the invention, the method can realize the evaluation on the stability of the ground surface close to the tower position and in the preset width range of the transmission circuit route, thereby meeting the evaluation requirement on the stability of the foundation of the ultra-high voltage line passing the mining infection zone. The embodiment of the invention also provides a method for erecting the tower of the mining infection zone, which ensures smooth construction of the ultra-high voltage line in the mining infection zone.

Description

technical field [0001] The invention relates to the technical field of foundation stability assessment, in particular to a foundation stability assessment method and a tower erection method in mining-affected areas. Background technique [0002] Large-scale coal mining will have mining impacts around the mining area, which is the main reason for ground subsidence, pit collapse, cracking, and damage to buildings on the ground in the mining area. [0003] The stability of the foundation in the area affected by coal mining is crucial to the selection of UHV tower foundations and the laying of transmission lines. Therefore, it is necessary to evaluate the stability of the foundation in the area affected by coal mining and determine the tower erection plan accordingly. At present, there is no systematic foundation stability assessment method for the large-area coal mining impact area of ​​UHV lines. Contents of the invention [0004] In view of this, the purpose of the present...
