湖北大冶国储库某库地基质量事故原因分析

Analysis on the Foundation Quality Accident of Some National Grain Storage of Hubei Daye

主要介绍了湖北大冶国储库某库地基强夯处理过程及地基质量事故 ,根据震动理论探讨了强夯的机理 ,认为强夯后的地基具有双层构造 ,上层是强夯实层 ,下层是强夯弱层 ,强夯实层的下限深度可视为强夯的有效加固深度 ,强夯弱层的下限深度可视为强夯的影响深度 ,分析了造成地基质量事故的原因 ,提出相应的处理措施。

The paper mainly introduce the foundation treatment procedure by dynamic compaction and the foundation accident in Hubei Daye, discuss the mechanism of dynamic compaction according to the theory of vibration, consider that the compacted foundation have a double layer structure. The upper layer is entirely compacted layer, the lower layer is poorly compacted layer. The lower limit depth of the entirely compacted layer can be considered as the effective improvement depth and the lower limit depth of the poorly compacted layer can be considered as the influence depth. This thesis analysis the reason of the foundation accident and hold out corresponding treatment demarcate.
