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- 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. The shape and layout of caverns are optimized; and then the most stable and safe cavern shape and layout are obtained. The results of study indicate that the deformation stability theory pro vides practical and effective theory and method for the optimization design of cavern shape and caverns layout of salt rock gas storage.
