Stability Evaluation of Highway Near Mined-Out Region
The stability evaluation of highway near a goaf is a key problem in highway construction projects. The goal of this research is to analyze the surface deformation of the highway No.108 in Baoshui area. Both Probability Integral Method (PIM) and Finite Difference Method (FDM) are used and compared to deal with this problem. The main aspects of this research consist of surface subsidence calculation and prediction of surface residual deformation. The results calculated by probability integral method and finite difference method are mainly in agreement,and they are in accord with surface deformation observation results of some sections. So these two kinds of method are proven to be effective in dealing this problem. Moreover, the surface residual deformation was predicted by using numerical simulation based on FLAC3D. To ensure the highway No.108 security, backfill grouting should be carried out in the areas where collapse pits and ground fissure are found near the highway.
