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。本文结合工程地质及现场效果,通过技术经济分析了地震液化区不同的地基处理方案,综合认为振冲碎石桩复合地基比钻孔灌注桩经济,技术上更为优化。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 our design＇s request, a ground treatment usually can be taken to strengthen it. According to the engineering geology and the field effect ,this paper introduces the different schemes for strengthening the earthquake liquefacient country foundation from the aspect of technical economy. The results show that the vibro-replacement stone column is better than the driven cast-in-place pile from the aspect of technology and economy.
