摘要
本文利用顾桥煤矿1111(3)综采面地表移动观测站数据处理成果和外业数码相片,分析了建构筑物破坏现象产生的机理及其影响规律。得出相关结论:建筑物产生破坏和变形主要原因是曲率和水平变形的影响,在其作用下,采动区地面建筑物砖墙上出现裂缝。通过分析采动区上方建筑物砖墙上裂缝的分布规律,为合理加固和维修措施提供了依据,从而可以在建筑物受采动影响以前,根据地表变形预计的结果,对建筑物采取适当的措施,来减小地表变形对其影响。
The data of land surface movement observation stations and outdoor photographs obtained, which are near 1111 ( 3 ) coal mining face in Guqiao mining area, were used to study mechanism and laws of building deformation in tiffs paper. Correlative con- clusions were drawn: curvature and horizontal distortion are the main factors impacting on destruction and deformation of buildings, which caused brick wall on the surface of mining cracked. By analyzing the law of cracked brick wall in mining area, some principles were drawn for reinforcing and maintaining buildings, so that before buildings could be affected by mining, some measures could be taken to release the influence of land surface deformation on buildings by the estimated result.
