摘　　要：火力发电厂冷却塔对地基的承载力要求较高,在天然地基承载力或变形不能满足上部结构要求时,一般要采用人工方法对地基进行强化处理。本文通过工程实际,介绍了在火力发电厂冷却塔地基处理工程中振冲碎石桩技术的设计、施工、检测及效果。表明了振冲碎石桩在加固冷却塔地基工程中技术上是可行的,在施工质量和处理效果上可以满足要求,复合地基的承载力和稳定性都得到了较大的提高。Cooling tower for fossil-fired power plant have a high requirement of ground bearing capacity.When the bearing capacity of natural foundation or its distortion can not meet design＇ s request,a ground treatment usually can be taken to strengthen it.From the constructing work,the design,construction,detection and results of the vibroreplacement stone technology to strengthen the ground were introduced in this paper.The results show that this method is feasible technically and can satisfy the requirement of construction and treatment.The bearing capacity and stability of the ground have been raised greatly.

关 键 词：振冲碎石桩技术 施工要求 承载力 稳定性
