The genetic analysis of cracks of the ground and buildings in New Sujiali Village

Based on the survey results of cracks and the monitoring data of subsidence of the ground and building in New Sujiali Village, the cracks caused by non-mining factors are comprehensively and qualitatively analyzed with application of engineering geological analogy method. Meanwhile, it takes the FLAC^3D program to do the numerical simulation analysis about the buildings affected by the goaf. It also summarizes the causes of cracks on the ground and buildings, location and law due to mining and non-mining factors. Analysis shows that the cracks of the ground and buildings in New Sujiali Village, Shanxi Province is the interactional outcomes of surface deformation caused by subsidence, uneven settlement of foundation, river erosion and so on. The research results can provide basis for the restoration and reinforcement of the ground buildings in the mining area.
