【摘要】 危险化学品立式储罐底板腐蚀损伤易导致承载性能衰减，存在结构性撕裂风险。本研究针对储罐运行工况下底板腐蚀特点，系统研究底板剩余厚度、基础沉降量与承载性能的多参数耦合作用关系。通过构建钢基-涂层复合结构力学模型，阐明双层防渗结构应力变化，分析了复合结构全寿命周期内的关键风险因素。更多还原

【Abstract】 The corrosion of the tank bottom plate will weaken its bearing strength and may tear up the bottom plate in serious cases. Aiming at the problem of floor corrosion during the operation of vertical storage tank, this paper analyzes the relationship between floor thickness, foundation settlement and bearing performance. On this basis, the stress distribution when the coating material is combined with the steel base plate is analyzed, and the risk factors in the application of the composite structure are determined.更多还原
