摘　　要：通过大量文献研究和广泛工程调研,从6个方面综合论述了近期国内外新型岩土锚杆(索)的发展现状,即用于地下工程支护、城市基坑加固、腐蚀地质工程加固、软土地层工程加固、地下洞室抗爆以及边坡地震灾害治理的新型岩土锚杆(索)。在此基础上,分析了当前锚杆(索)发展中仍存在的主要问题,并指出了今后需要进一步开展的重要工作,包括针对深地下工程支护问题加强对屈服型锚杆(索)的研发,针对锚固工程耐久性问题加强对非金属锚杆(索)的研发,针对城市基坑工程加固问题加强对回收锚杆(索)的研发,针对软土地层工程加固问题加强对扩体型锚杆(索)的研发以及针对地下洞室锚固抗爆问题加强对新型抗爆锚杆(索)的研发。Through a great deal of literature research and extensive engineering investigation, the current development state of domestic and foreign new geotechnical bolts and cable-bolts is synthetically discussed from six aspects, such as the new geotechnical bolts and cable-bolts for underground engineering support, city foundation ditch reinforcement, corrosive geotechnical engineering reinforcement, soft soil stratum engineering reinforcement, underground cavern blast-resisting and slope seismic hazard cure. Based on the above discussion, the main problems still exist in current geotechnical bolt and cable-bolt development is analyzed and the important work which should be carried out in future is pointed out. It includes the development of yieldable bolt and cable-bolt for deep underground engineering support problem, the development of non-metal bolt and cable-bolt for anchor engineering endurance problem, the development of removable bolt and cable-bolt for city foundation ditch reinforcement problem, the development of body-expanded bolt and cable bolt for soft stratum engineering reinforcement problem, and the development of new blast-resisting bolt and cable bolts for underground carven blast-resisting problems.
