摘要
本文叙述的是在松软泥岩巷道中采用喷锚网—钢筋混凝士弧形板复合支护的工程实例。对一、二次支护的设计原则,时间和空间的匹配和施工顺序等进行了分析,并扼要叙述了关于弧形板强度、尺寸、接头形状、垫板材料和充填材料等的实验研究成果。
This paper discribes a case history of a composite support system using bolts, shotcrete, mesh and prefabricated are plates of reinforced concrete for a tunnel in mudstone. The design principle of primary and secondary support, the relation between the support system and supporting time and location, and the excavation and supporting sequence have been discussed in detail. Experimental results in laboratory about the strength, size and join shape of the are plate, the material of the pad plate and the filling material have been presented briefly.
