开采沉陷引起地表移动,建筑物基础与地基发生相互力学作用。为研究受采动曲率变形影响的建筑物基础的附加作用力,考虑了建筑物横墙荷载对纵墙基础的作用,提出建筑物纵墙地基反力的计算模型,推导出纵墙基础受到曲率变形影响下的附加作用力计算公式。研究结果表明:在正、负曲率变形的影响下,横墙荷载对纵墙基础附加弯矩的贡献不同,在地表正曲率变形作用下,横墙荷载增加了纵墙基础附加弯矩,而在地表负曲率变形作用下,反而可以减少纵墙基础附加弯矩。
Mining subsidence caused by the movement of the surface, the foundation of the building and the foundation mutual mechanical effect. In order to study the additional force of the building foundation affected by the deformation of mining curvature, the effect of the transverse wall load of the building on the foundation of the longitudinal wall is considered, the calculation model of the foundation reaction force of the longitudinal wall of the building is proposed, Calculation formulas of additional forces under the influence of deformation. The results show that under the influence of positive and negative curvature, the contribution of transverse wall load to additional moment of longitudinal wall foundation is different. Under the positive curvature of surface, the additional load of transverse wall increases the additional bending moment of longitudinal wall foundation, Negative curvature of the surface deformation, but can reduce the additional wall bending moment basis.
