摘　　要：将“钢筋砼梁”的分析原理应用于陶瓷内衬复合钢管的分析，得到的复合钢管径向压溃强度的计算公式不仅体现了材料几何尺寸的效应，而且反映出材料性能的影响：进一步分析表明，陶瓷衬层的弹性模量越高，复合钢管径向压溃强度就越高，这为材料结构设计提供了有价值的参考．The theory of analysis of reinforced concrete beam is applied to the study of ceramic-lined steel composite pipe. A new formula of radial crushing strength of composite pipe is presented, which includes both the geometry sizes and the properties of the materials. The results obtained from this formula show thatthe greater the elastic modulus of ceramic lining is, the higher the radial crushing strength of the composite pipe is. This provides a valuable information for the structural design of the composite pipe.
