摘要
文中系统分析了地下巷道口岩受单组和多组弱面对其稳定性的影响，提出了利用各种支护方式（砌碹、锚喷等）补偿围岩自力强度和提高围岩稳定性的理论分析方法。工程实例研究表明，该法在现场评判地下巷道围岩稳定方面简便实用。
aving systematically analysed the influence of a group or groups weak planes on the stability of the rocks surrounding undrground roadways, the paper put foward the theoretical analysis method for enhancing the stabilityof the surrounding rocks by compensating its strength sith various supporting such as arching shotcreting, etc. Casehistory of engineerings indicates that the method is sinple and practical in judging the stability of the surrounding rocks of underground roadways.
