摘　　要：针对建设场地的工程地质特点,对2种不同型式的冷却塔地基处理方案进行了比较,确定采用钢筋混凝土灌注桩地基处理方案。采用TSH3SCOQ双曲线自然通风冷却塔结构静力计算程序(有矩理论)对不同桩径(桩径为0.8m和1.2m)、不同布桩形式的桩基方案进行了的技术经济比较,最终确定了每对X支柱下布置6根直径1.2m灌注桩这一合理、经济的桩基设计方案。According to the geological characteristics of construction site,the treatment schemes for two types of cooling tower foundation are compared,and the reinforced concrete（RC） pile foundation is selected.Then,the technical and economic comparisons are implemented on several pile foundation schemes with different pile diameters（0.8 m and 1.2 m） and pile layout,by using TSH3SCOQ static calculation program（moment theory） for hyperbolic natural draft cooling tower.Finally,a reasonable and economic design scheme of pile foundation is determined,in which six bored piles whose diameters are 1.2 m are arranged under each pair of X pillar.
