摘要
为研究采动区地表变形对砌体结构的影响规律,结合实际工程,利用有限元软件ABAQUS对某煤矿3105工作面1号宿舍楼进行模拟,分析砌体结构在地表变形作用下的应力状态、受力机理及易损部位,为采动区砌体结构抗变形加固提供依据。结果表明:倾斜变形对砌体结构影响最小,曲率变形影响最大。曲率变形作用下,结构损伤较严重且主要集中在结构中部和两端;地表水平拉伸变形对砌体结构影响大于压缩变形,两者对底层墙体影响显著,对上层墙体影响较小。
In order to study the influence law of surface deformation in mining subsidence area on masonry structure,the finite element software ABAQUS was used to build a model of the No.1 dormitory building on the 3105 working face of some mine area combining with engineering practice.The stress state,stress mechanism and damageable zone of masonry structure were analyzed under the surface deformation,which provided a foundation for anti-deformation reinforcement of masonry structure in mining subsidence area.The results show that inclination deformation had the least influence on masonry structure,curvature deformation had the greatest influence.Under the effect of curvature deformation,structural damage was serious and mainly concentrated in the middle and two ends of the structure;the surface ground horizontal tensile deformation had more influence than horizontal compression deformation on the structure,both had a significant effect on structure ground walls and a little effect on structure upper walls.
