摘　　要：由中国岩石力学与工程学会于2008年6月组织的中国科协第21期新观点、新学说学术沙龙,集中对围岩分区破裂现象以及相关的理论问题进行了讨论,内容涉及近期有关围岩分区破裂的研究成果,包括现场实测和实验室试验工作及分析,围岩分区破裂的形成机制、分区破裂各种现象的解析与数值分析方法,会议还讨论了论题的意义及其研究方法等方面的热点问题。对围岩分区破裂的研究具有探索性,目前的认识尚存在许多争论。对这一工作的讨论,不仅可以促进课题成果及其科学性,而且对整个科研工作的认识和处理方法也有启发性的影响。A discussion on zonal disintegration phenomenon and related theoretical problems in surrounding rocks of deep roadways were held in an academic salon about new ideas and new theories by Chinese Society for Rock Mechanics and Engineering. The contents of this academic salon cover the latest research achievements on zonal disintegration, e.g. measurement in-situ stresses and experimental research result analyses of a laboratory, explanation and different phenomena and their formation mechanisms about zonal disintegration, and the development of numerical analysis methods. Moreover, some hot issues such as the meaning and research methods about zonal disintegration are also discussed. Although the study of zonal disintegration is in a groping state and some controversies on present research results still exist, the discussions are very helpful for scientific achievement in this research subject and have an enlightening influence on acknowledgement and disposal methods of this research work on zonal disintegration.
