Method for predicting highway pavement damage under influence of coal mining subsidence
The embodiment of the invention discloses a method for predicting highway pavement damage under the influence of coal mining subsidence, relates to the technical field of mining subsidence and geophysical prospecting, and is invented for conveniently improving the accuracy of determining the potential damage position of a highway pavement. The method comprises the steps that before coal mining, ageological radar method is used, a roadbed and the pavement of a highway within the starting and stopping range influenced by the coal mining subsidence are detected with two or more kinds of electromagnetic wave frequencies, and a first detection result corresponding to the electromagnetic wave frequencies is obtained; a first damage position is determined according to the first detection result;during mining, the geological radar method is used for detecting the roadbed and the pavement with the two or more electromagnetic wave frequencies, and a second detection result corresponding to theelectromagnetic wave frequencies is obtained; a second damage position is determined according to the second detection result; based on the first damage position and the second damage position, the development condition of roadbed and pavement damage is determined; and the potential damage position of the highway pavement is further determined. The method is suitable for determining the potentialdamage position of the highway pavement.
