Underground mining causes the ground to deform, leading to the destruction of buildings. Horizontal strain is one of the most important causes of damage to strip foundation buildings. However, related research is insufficient and the mechanism behind building damage caused by horizontal strain remains unclear, resulting in several difficulties in performing coal mining under villages. In this study, interface slip and soil pressure caused by the horizontal strain of ground transfer between soil and buildings are investigated, and stress concentration in buildings driven by soil movement is considered the primary cause of building damage. The influences of the mechanical parameters of soil and the geometric parameters of a building on stress distribution inside a building are analyzed by establishing a stress distribution model of a building under different ground horizontal strains. Softening the foundation or designing deformation joints inside a building can reduce the influence of horizontal strain on a building. This research can provide an important reference for performing coal mining safely under villages and designing building protection against ground horizontal strain.

“…Thus, the influence of soil shear deformation should be considered when studying the transfer of deformation from ground to buildings [5]. Kahi analyzed the soil-structure interaction caused by surface curvature deformation on the basis of the Winkler and Euler-Bernoulli beam models; the author also examined building damage caused by structural heterogeneity [6]. Neha investigated the characteristics of ground subsidence caused by underground water depletion and then analyzed the characteristics of house damage caused by different subsidence rates [7].…”

Underground mining will cause the ground to deform, leading to the destruction of buildings. Horizontal strain is one of the most important causes of damage to strip foundation buildings.

The deformation of existing pipelines caused by the tunneling of a shield machine along curved sections has not been sufficiently researched, and a corresponding theoretical prediction formula is lacking. This paper derives a prediction formula for the deformation of an existing pipeline caused by shield machine tunneling along a curved section. Further, a finite difference model (FDM) corresponding to an actual project is built. Finally, the deformation of the surface and existing pipelines caused by shield machine tunneling along the curved section is analyzed. The research results show that the results of theoretical prediction, FDM calculation, and field monitoring data are consistent. In addition, the deformation of the surface and the existing pipeline are asymmetrically distributed when the shield machine tunnels along the curve section instead of symmetrically distributed (for straight line segment). When the pipeline is perpendicular to the tunnel axis, the maximum deformation position of the existing pipeline deviates from the tunnel axis by about 0.5 times the tunnel radius. In addition, as the angle β between the pipeline axis and the tunnel axis increases, the maximum deformation position of the pipeline gradually approaches the tunnel axis.
