中文摘要：

高地应力、高地温、高渗透压以及强时间效应使得深部裂隙岩体表现出一定的延性、蠕变性等软岩力学特性,现有锚固理论落后于工程实践的现状,导致许多锚固工程设计多采用经验、半经验方法。几十年来,国内外诸多学者对深部岩体锚固机制开展了大量现场、室内试验及数值计算工作,岩体锚杆锚固作用机制方面的理论研究取得了丰硕成果,但由于深部岩体所处地质条件的复杂性,这些成果普适性和准确性较低。结合已有的锚固理论,运用合理的数值模拟方法与现场、室内试验对岩土锚固机制进行深入研究,进而指导锚固工程设计施工具有重大意义。对深部裂隙岩体锚固机制研究现状进行了系统全面的总结,归纳分析了该研究领域存在的关键科学问题,主要包括：选择合理的锚固力学传递计算模型、正确描述锚固体应力分布规律、建立合理的锚固界面力学模型。深部裂隙岩体锚固机制研究应综合考虑工程应用效果和加锚岩体形态、加锚构件效应等因素。

英文摘要：

The high ground stress,high temperature,high osmotic pressure and strong time effect cause the deep fractured rock to show certain ductility and creep in mechanical characteristics of soft rock. The current anchoring theory lagging behind the engineering practice leads to the common usage of the empirical and semi-empirical methods in most of the anchoring engineering. During the last several decades,a number of on-site and laboratory tests and numerical calculations were carried out by many scholars home and abroad,and significant achievement in the theoretical research of bolt anchorage mechanism in rock mass were made. The universality and accuracy of these results are low because of the complexity of deep geological conditions. Combined with the existing anchorage theory,it is of great significance to use a reasonable numerical simulation method and on-site and laboratory tests to investigate the rock and soil anchoring mechanism and to guide the design and construction of anchoring engineering. Systematic summary was made regarding the deep fractured rock anchoring mechanism,and the key issues for the study of the deep fractured rock anchoring mechanism were concluded,including the choose of a reasonable calculation model for anchoring force transfer,the correct description of the stress distribution of the anchoring force and the establishment of the reasonable mechanical model for anchoring interface. The factors such as the effect in engineering application,the condition of anchoring rock mass and the effect of anchoring components should be considered in the research of the deep fractured rock mass.
