摘　　要：笔者针对盐穴储气库溶腔夹层的受力与破坏特征,运用应用梁的弯曲理论,建立了夹层简化力学模型,并应用该模型进行了求解,得到了夹层剖面内弯曲剪应力和弯曲正应力分量的分布规律,计算结果与应用小挠度薄板弯曲理论计算结果基本一致。但应用本文所建简化力学模型求解时,不依赖于夹层弹性模量和泊松比。研究成果为盐穴储气库溶腔夹层的力学分析提供了一种简单有效的计算方法,方便现场应用。We established a simplified mechanical model of interlayer and solved it by bending theory of tapered, unsymmetric beam based on the characteristics of small deflections and collapsing of interlayer in salt caverns gas storage. Stress distribution rules were analyzed by this model. Distribution characteristics of various stress component in sections of interlayer were computed combined with engineering examples. The result was in accordance with that of bending theory of thin plates with small deflections, and it was independent of elastic modulus and possion ratio. This simplified computing method was provided for mechanics analysis of interlayer in salt caverns gas storage.
