CFG桩在某大型油罐局部地基处理中的应用
摘要:通过工程实例,介绍CFG桩在大型油罐地基局部处理中,既有效提高软弱地基强度,又最大限度保持不同地基变形协调一致的处理方法。针对油罐体型的特殊性,采用了沿油罐圆心环形布桩,并且根据不同地段地基土性质的纵横向差异采用不等距布桩的方案。复合地基处理效果理想,达到了预期的设计目的,为类似工程的地基处理提供了一种新的设计理念,供类似工程参考。
Abstract:The paper introduces the handling methods of CFG pile in local ground treatment of large oil tank through engineering practice, which not only improve the strength of soft ground effectively, but also utmostly keep the coordination of different ground deformation. In view of the specialty of the tank shape, along the tank of the circle loop piles are adopted and the scheme of unequally spaced piles are adopted according to the vertical and horizontal differences of subsoil properties of different sections. The treatment effect of composite foundation is ideal and achieves the desired design goal. It provides a new design concept for the ground treatment of similar projects and could be a reference.
