摘　　要：地球演化、地下水系统、岩体工程和地质灾害涉及不同尺度的岩体结构,由于地下岩体结构数据匮乏,实现区域岩体结构精细化分析是科学难题.本文基于岩体结构跨尺度调查研究进展,归纳岩体结构精细化分析存在的问题,提出应用地球系统科学理论解决问题的设想和技术方案.岩体结构与演化历程、温压环境(PTt)密切相关,需要从系统科学角度探究不同尺度结构面的协同演化机理和跨尺度岩体结构精细分析理论;将地球系统科学与岩体结构现代探测、测试和模拟技术相结合,提出了区域岩体结构跨尺度研究的技术方案、分析理论和实现算法,以期突破区域岩体结构精细化分析的瓶颈问题.Earth evolution,groundwater system,rock engineering and geohazards are related to rock mass structures of different scales.Due to the data deficiency on the structure of underground rock mass,it is a significant challenge to realize the regional elaborated analysis of rock mass structure.Based on the summary of research progress of multiscale rock mass structure investigation,in this study it lists the problems in the elaborated multiscale analysis of rock mass structure.Applying the theory of earth system science,the ideas and technical solutions for these problems are proposed.Rock mass structure is closely related to the evolution process and surrounding environment(pressure-temperature-time,PTt).It is necessary to explore the co-evolution mechanism of discontinuities on different scales and the elaborated analysis theory of multiscale rock mass structure from the perspective of system science.This study combines earth system science with modern survey,experiment,and simulation of rock mass,and proposes a multiscale research approach of rock mass structure combining“PTt-mechanical model-menergy dissipation-discontinuities”.The approach is expected to realize the regional elaborated analysis of rock mass structure.
