| 摘 要： | 为解决盐岩储气库洞室形状以及库群布置的优化设计问题,将变形加固理论发展和完善为变形稳定理论,把塑性余能与强度折减系数的K-ΔE关系曲线作为储气库群的整体稳定性判据。在变形稳定理论的基础上,对不同形状和布置方式的洞室的整体稳定性进行定量评价,优化分析了洞室形状以及库群的布置方式,进而获得最具安全稳定性的洞室形状和布置方式。研究结果表明,变形稳定理论为盐岩储气库洞室形状和洞群布置方式的优化设计提供了一套实用有效的分析理论和方法。

| Abstract: | In order to solve the problem of optimization design for cavern shape and caverns layout of salt rock gas storage,the deformation reinforcement theory is developed and improved into deformation stability theory.The relation curve of plastic complementary energy versus strength reduction factor,K-relation curve,is used as the global stability criterion of cavern cluster.On the basis of deformation stability theory,the global stability of caverns with different shapes and layouts is quantitatively assessed.Th... |
