摘　　要：提出了定量评价锚杆对节理加固作用的理论公式,并利用提出的公式研究了影响锚杆加固作用的一些重要因素,探讨了提高锚杆加固作用的有效途径。A method was presented for reasonably evaluating of bolts reinforcement of the shear strength of rock joints. The effective approaches to improve the bolts reinforcement efficiency are discussed by analyzing several important factors which have influences on the bolt reinfrocement efficiency. Therefore the defects of relevant analysis proposed before by many authors have been improved.
