Abstract: It is of challenging and emergency problems for hazardous assessmemt and treatment technology on the mined-up regions under the highway tunnels. Based on the DaYuliang tunnel project which through the mined-up regions, that in Liulin section of Qingdao-Yinchuan highway, the 3-D computation models have been built by using the MIDAS/GTS finite element program, and numerical simulation analysis of the ground surface deformation response, and tunnel lining structural deformation as well as its structural force, that were generated in the process of the step-by-step mining, grouting treatment after mined-out coal in Qinglong, and then excavated double-track tunnels. The degree of surface deformation in different working conditions has been revealed, the ground subsidence basin characteristics and the subsidence central position have been defined, the deformation and force bearing key parts of tunnel-lining have also been predicted. These have important theoretical meaning to direct the practice to meet the project requirements of strength, stiffness and stability of tunnels structure.
