A mechanical model of the interlayer is established and solved by bending theory of thin plates with small deflections for collapsing of interlayer in salt caverns gas storage. The stress distribution rules and collapsing conditions of the interlayer are analyzed with the mechanical model. A computing method is provided for ultimate span of the interlayer. Distribution characteristics of various stress components in the section of the interlayer are computed with engineering examples, and the collapse of position under the conditions of varying thickness of interlayer is computed. The results show that the maximum shear stress occurs in the middle plane of the fixed end of the interlayer, and the maximum normal stress occurred in the upper and lower end faces of the fixed end of the interlayer. Shear failure occurs at the fixed end of the interlayer when the maximum shear stress reaches its limit value. Tensile failure occurs at the fixed end of the interlayer when the maximum normal stress reaches its limit value. Engineering practice has proved that the greater the thickness of the interlayer, the larger the collapsing span. A theoretical basis and computing method are provided for prediction of collapsing of interlayer in salt caverns gas storage., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=K7lK5fjyv1AzUbNmF6hJAQ==, pdfFileSize=1591706, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
