Key Technology for the Structure Design of Mining Metro Station in Rock Strata

Abstract:

Focused on the mining method, the parameters of primary support, and the design method for the interface of metro station and air duct structure, what are encountered during the design of mining station in rock strata. Through the combination of numerical method and theoretical analysis, and the comparison with field measured data, we know that double-side-wall heading method is safe and feasible, design method based on plastic stage can be used for the checking of primary support structure, and the combination of support in advance and closed steel frame can insure the safety of the interface of metro station and air duct structure. Through analysis, the changes of displacement and stress are focused around vault and arch springer, and the decrease and increase of safety factor during construction are also made clear. The study can offer a reference for the similar project in the future.
