【摘要】 本文简要介绍了抚顺煤田的区域地质背景及受灾楼房调查结果,并对房屋建筑破坏特征进行了分析。同时,对大地测量结果、地质勘察及试验结果进行了讨论,结果表明:煤田开采诱发了浑河断裂抚顺段的局部活动。最后,综合分析得出断层活动引起的地基不均匀沉陷是造成该市建筑破坏的主要原因,且断层引起的地基不均匀沉陷不同于一般软基不均匀沉陷。更多还原

【Abstract】 In this paper,the geological setting and the investigation on the destruction of buildings in Fushun coalfield is introduced briefly and the characteristic of destruction of buildings is analyzed.In the meantime,the data of geodetic measurement,geological investigation and test are also analyzed,and the analytic results show that the local motion of Fushun segment on Hunhe fault is caused by coal extraction.Finally,the comprehensive study comes to the conclusion that the main reason for causing destruction of buildings in Fushan is the inhomogeneous settlement of ground triggered by fault motion,and the inhomogeneous settlement of ground caused by fault motion is different from the inhomogeneous settlement of soft ground.更多还原
