采煤沉陷与断层相互作用引起地表建筑破坏特点分析

针对抚顺煤矿计算采沉区以外批量房屋损伤，通过现场变形测量、地质勘查。得到了损伤房屋的分布、结构类型、破坏特点、场地条件等基本数据。结合区域地质构造和结构力学分析，提出了构造断层与采煤沉陷相互作用导致局部区域岩体运动呈现“多米诺骨牌”形式，总体趋势向沉降盆地中心运动，在断层线出露地表处出现“反陡坎”，揭示了在计算的正常沉陷范围以外地表若干建筑差异沉降破坏的形式与采沉方向相背的原因，据此提出了针对性的治理方案。

Analysis of building damage caused by interaction between faults and coal mining subsidence

Aiming at the damage analysis of group buildings in a coal mine city,by combining the results of field survey,geological prospecting,regional geological structure analysis as well as engineering mechanics analysis,a dominoes movement theory which describes the motion of parallel rock blocks induced by coal mining is proposed.Because of the interaction between parallel faults and coal mining,on the ground surface appears inverse bank along the fault line,thus the abnormal cracks appearing on the buildings are explained,and corresponding countermeasures are presented.
