| Abstract: | Hazard assessment is one of the difficult technical issues for expressway construction in mined-out region.The characteristics of residual subsidence and deformation are studied.The basic principle and key points of empirical formula method,prediction and evaluation method,FEM are introduced.According to the three stage of highway design,the content and target are respectively summarized.The evaluation and process are also put forward.Finally,the computing example indicates the validity of the three methods. |
