摘　　要：混凝土储油罐所受拉应力主要为温度应力,开展温度应力模型试验是研究罐体受力规律的重要方法,根据相似理论来设计模型试验成为首要问题。文章根据相似理论,推导出混凝土储油罐温度应力模型试验的相似条件,并确定了试验相似常数,进而提出储油罐模型温度荷载加载方式,最后通过数值仿真分析手段进行了验证。The main tensile stress that a concrete oil tank bears is the temperature stress.Temperature stress model experiment is an important method to study the stress rules of the oil storage tank,and it should be designed according to the similarity theory.Based on the similarity theory,the similarity conditions of the concrete oil storage tank temperature stress model experiment are derived,and the similarity constants are de-termined.The loading process of thermal load in the oil storage tank model experiment is proposed,and it is verified by the numerical simulation.
