摘　　要：国内大型储罐基础采用凸形顶面钢筋混凝土环墙或外环墙基础。罐底板受压,易失稳起褶皱。这种基础施工周期长,工序复杂,且没有环保措施,一旦储罐底板开裂,储液泄露,污染地基、地下水和环境。针对以上问题,提出环保型大型储罐凹形护坡式碎石环墙基础,打破国内规范限制,很好地解决了以上问题,并且有很好的经济效益和社会效益。The convex reinforced concrete ring wall or outside ring wall is used for large storage tank foundation in China.The bottom plates of tank stand pressure and apt to develop ripples due to lack enough stability.The construction period of the foundation is long,and the construction procedure is complex.Storage liquid would leak out and pollute subgrade,groundwater and environment when the bottom plates of the storage tank crack.Aiming at the problems herein before,it is put forward a new environmental protection and concave crushed rock ring wall shoulder for large storage tank foundation that acts against the national specification but the problems hereinbefore could be solved.This foundation would bring better economic and social benefits.
