摘　　要：储罐地基基础是石油化工装置的基本构筑物,特点是体型和荷载庞大,对地基要求较高。由于环墙式钢筋混凝土基础具有较大刚度、较强抵抗不均匀沉降能力、较小占地面积和经济性等方面优势,储罐基础经常采用这种型式。通过某工程2×10~4 m^3重油储罐基础设计实践,探讨SH/T 3068—2007《石油化工钢储罐地基与基础设计规范》和GB 50473—2008《钢制储罐地基基础设计规范》在基础计算工况、计算公式和参数取值等方面存在的差异,以及对计算结果产生的影响。因储罐荷载较大,且建在软弱地基上,故采用CFG桩复合地基取得成功,项目运行多年效果良好。The foundation of storage tank is the basic structure in petrochemical plants.Characterized by huge size and load,storage tank has high requirements for its foundation.Ring wall reinforced concrete foundation is often adopted due to its advantages of great stiffness,high resistance to uneven settlement,less land occupation and good economics.Based on the engineering practice of the foundation of a 20,000 m 3 heavy oil storage tank,this paper discusses the differences between SH/T 3036-2007 Specification for Design of Steel Storage Tanks Subgrade and Foundation in Petrochemical Industry and GB 50473-2008 Code for Design of Steel Tank Foundation in the calculation conditions,calculation formula and parameter values of foundation as well as their effects on calculation results.CFG pile composite foundation is successfully used for this heavy load storage tank built on soft soil.The project has been running well for many years.
