Abstract


The paper giant Guodian Hebei Longshan power plant special railway lines magnetite mined-out area for the case study , to carry out survey goaf stability evaluation , the choice of design and governance of the governance program reinforced roadbed deformation numerical simulation . Are as follows: 1) According to the the goaf distribution status and characteristics of , the use of comprehensive geological survey methods to survey the mined-out area , have complete control of the the goaf distribution range , the development of the magnetite mining characteristics of ground deformation and the Chamber . 2) According to the survey results of the mined-out area of goaf stability evaluation , the results of the evaluation of the mined-out area does not meet the requirements of the new railway line base , you need to governance . 3 ) demonstration and filling pressure grouting method to govern the mined-out area , and grouting treatment range , grouting parameters , drilling layout , grouting implementation approach to design . 4) the Fast Lagrangian finite difference program FLAC2D subgrade settlement deformation after grouting reinforcement numerical analysis, research center line extending to both sides different filling and filled with different intensity slurry roadbed settlement deformation the difference between the findings suggest that the actual reinforcement processing and filling slurry strength to meet the subgrade settlement deformation control requirements . The research results can provide theoretical references for the Civil Engineering .
