随着国民经济和国防建设的发展，地下深部岩体工程越来越多，如深达数千米至数千米的矿山（如南非的金川镍矿、金矿等），锦屏二级水电站引水隧洞及辅助隧洞、核废料深部地质堆积及深部地下防护工程等，在采用爆破等方法开挖深部岩体时，围岩的变形与破裂呈现出一些新的科学特征现象，除了深部岩爆和挤压地层中隧洞的大变形外，分带崩解现象引起了国内外岩土工程和岩石力学领域学者和工程技术人员的广泛关注，在国内外对分带崩解现象的实验和理论研究的基础上，总结了带状崩解的主要特征及相应的变化规律，揭示了带状崩解发生的机理;提出了该领域的研究重点，并介绍了国内对带状蜕变现象的实验和理论研究。
With the development of national economy and defense works,there are more and more deep underground rock wass engineering,such as the mines with depth of thousand to several thousands meters(Jinchuan nickel mines and gold mines in South Africa,etc.),water diversion tunnels and auxiliary tunnel of Jinping II hydropower station,deep geological deposition of nuclear waste and deep underground protection engineering.While the deep rock mass are excavated by the blast or other methodst,he deformation and fracture of the surrounding rock show several new scientific characteristic phenomena.Besides the deep rockburst and large deformation of tunnel in squeezing ground,the phenomenon of zonal disintegration attracts the attentions of scholars and engineers in the fields of geotechnical engineering and rock mechanics in the world.Based on the experimental and theoretical researches of zonal disintegration phenomenon at home and abroad,the main characteristics and corresponding changing laws of zonal disintegration are summarized.It is revealed the mechanism for the occurrence of zonal disintegration;and the emphasis in this field is proposed.Also the domestic experimental and theoretical investigations of zonal disintegration phenomenon are introduced.
