摘　　要：临界锚固长度和极限锚固力对于岩土锚固工程设计至关重要。这两个概念彼此相互联系。本文分析了临界锚固长度和极限锚固力的概念,综合论述了近年来临界锚固长度和极限锚固力的研究进展。在此基础上,指出了今后需进一步开展的研究工作:1系统深入研究临界锚固长度问题,给出可确定临界锚固长度的科学方法;2建立合理的锚固段非平均剪应力分布模型,给出实用的基于非平均剪应力分布理论的极限锚固力计算方法。Critical anchorage length and limit anchorage bearing capacity are very important for geoteehnical anchorage engineering design. The two concepts are related to each other. The concepts of critical anchorage length and limit anchorage bearing capacity are analyzed. It reviews the research progress of critical anchorage length and limit anchorage bearing capacity. It points out research topics in future：①to systematically and deeply research critical anchorage length, and give out the scientific method determining critical anchorage length ; ②to establish reasonable mode for shear stress distribution of distribution along anchor section, and give out practical limit anchorage bearing capacity calculation method based on non-average shear stress distribution theory.
