Research on Allowable Deformation of Highway Influenced by Coal Mining Subsidence

Abstract:

The paper put forward allowable deformation of highway is the premise of the study on problems of highway influenced by coal mining subsidence. Base on the analysis of correlative regulations and highway characteristics, the research pointed out a certain deformation value is not suitable for judging the safety of highway influenced by coal mining subsidence and the criterion of allowable deformation with considering the structure and the material of highway must be established. Using curvature as the allowable deformation index, The paper derived the criterion formula of the allowable deformation of highway and calculated the allowable deformation interval of common highway in China. The achievement is useful for solving correlative problems in the future.
