Original Paper


The deformation damage of buildings above the subsidence area is not only caused by the unstable deformation of the mining residual cavities and fractures, the time effect of soil compression is also an essential consideration, at the same time, the additional stress of the new building group in the mining-induced subsidence area is often influenced by multiple building loads. The physical properties and thickness change of soil layer are studied by drilling and laboratory test, the corner method is used to divide the load of building group and calculate the additional stress of foundation, the magnetotelluric imaging technique is used to investigate the distribution of mining residual cavities and fractures in the mining-induced subsidence area of the Shandong blue ocean pilot e-commerce industrial park, and the superposition prediction method and additional stress analysis method are used respectively to evaluate the stability of the foundation. The results show that the secondary consolidation settlement of soil layer accounts for about 10% of the residual deformation of subsidence area, the additional stress obtained by the corner method is 0.1935P. The evaluation results show that the proposed building will be affected by the unstable deformation of the mining residual cavities and fractures in the subsidence area. The evaluation results of the two methods are similar, it reflects their respective effectiveness. The two methods should be combined to evaluate the stability of the foundation in the engineering application.
