英文摘要 | The surface subsidence above gas storage caverns in rock salt is inevitable during operation, and its prediction and control are of great significance for the safe operation of gas storage caverns. Based on mechanical theory, the surface deformation caused by the shrinkage of a gas storage cavern in rock salt is simplified into a mechanical model for analysis. The overlying strata are treated as elastic multi-layer thin plates and the rock salt as a semi-infinite body. The boundary displacement caused by the volume change of a spherical cavern in an elastic layered semi-infinite body is solved. Using the concept of elastic equivalent surface force and introducing the calculation of cavern creep shrinkage volume, an analytical solution is obtained of the multi-layer thin plates model for the surface subsidence caused by the spherical cavern creep shrinkage. The model shows a good agreement with the numerical simulation. Through the concept of the key strata in mining subsidence, the influence is analyzed of the elastic modulus of the different rock strata in the overlying strata that dominate the subsidence. The results show that the subsidence at the ground center decreases with the increase of the elastic modulus of the overlying strata. The subsidence curve tends to be flat. The research can provide theoretical reference and guidance for the prediction of surface subsidence above gas storage caverns in rock salt. |
