软岩巷道新型网壳锚喷支架静力分析及其应用

Static analysis and application of a new kind of shell bolting and shotcrete support

简述了网壳锚喷支架的技术特点和静力分析,介绍了网壳锚喷支架工业性试验方案及试验结果,达到用较少材料又提高喷层支撑能力与让压的目标,证明网壳锚喷支架是一种结构合理、工艺简单、能承受强大地压及采动荷载的新型支架。

The shell bolting and shotcrete trestle used in the soft rock tunnels were analyzed. The static analysis was also accomplished. The result of the practical test of the new bracing shows that it can improve the bracing ability with less material. In a word, the shell bolting and shotcrete support are wellstructured,which can sustain great ground stress and can be constructed easily.
