摘　　要：在分析软岩锚喷支护机理及其破坏特征的基础上，探讨了破坏岩石锚固组合拱承载能力、支护载荷、组合拱合理厚度和合理锚杆长度的理论计算问题．所建议的计算公式，与实际符合较好．研究成果对于分析软岩锚喷支护机理和软岩支护是有益的．Based on analysing the failure mechanism and characteristics of bolt shotcrete support, the author discussed theoretically the problems of calculating the load capability, acted loads, rational thickness of a reinforced broken rock arch and the reasonable length of bolt. The suggested equations for the calculation tally well with actual situations. The research is of significance for analysing the mechanism of bolt shotcrete supporting and the design of successful supports in soft rocks underground.
