摘    要:本文简要介绍了抚顺市的场地环境和建筑破坏特点,并做了相关分析.若干场地进行的大量地质勘察和试验结果表明,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.同时,本文亦分析了断层活动与地下采煤造成地壳应力失衡的必然联系.

关 键 词:场地环境  结构破坏  断层活动  地基不均匀沉陷

Abstract:In this paper, the site environment and the characteristic of destruction of some buildings in Fushun city is introduced briefly and some relative analyses are done. Geological examination and testing study in situ reveal that the main cause for the destruction of buildings in Fushan city is the inhomogeneous settlement of ground triggered by fault motion. The inhomogeneous settlement of ground caused by fault motion is different from the inhomogeneous settlement of soft ground. In the meantime, the inevitable relationship between the fault motion and the out-of-balance of the crust stress caused by underground coal extraction is analyzed.
Keywords:site environment  structure destruction  fault motion  inhomogeneous settlement of ground
