摘要
近年来纤维增强喷射混凝土在地下工程中的应用成为岩土力学领域的研究热点之一。系统介绍了纤维增强喷射混凝土的常规类型,总结了其在地下工程中应用的性能特点。结合大型水封油气储库的工程特点,探讨了对喷射混凝土应用于地下水封油气储库工程的相关技术要求。从而,通过对比分析各种加强纤维的性能指标差异,探讨了其在大型水封油气储库领域的应用前景。最后,在技术上对未来发展方向进行了展望,结论对于地下水封油气储库工程设计与施工具有重要指导作用。
In recent years,the application of fiber-reinforced shotcrete in underground engineering has become one of the research hotspots in the field of geotechnical engineering.The conventional type of fiber reinforced injection concrete is introduced,and its perf-ormance characteristics in underground engineering is summarized.Then,the technical requirements of the injection concrete are discussed for the application prospect of its advantages in large water and oil storage and oil and gas storage.Finally,the development direction of the industry is prospected,and the relevant conclusions can be used by the colleagues in the industry.The basic principle,structure and characteristic of large scale underground water-sealed storage caverns is introduced.Then its brief development history is summarized to three stages.On this basis,the key technical problems which is faced by such projects are explained combined with engineering experience.Finally,several characteristics of this technology are summarized,and some conclusions can be used as reference for colleagues in related research.
