| 摘 要： | 根据隧道掘进机(TBM)施工进度将围岩分为施工条件好、施工条件较好、施工条件较差和施工条件差4个等级。利用模糊数学方法，采用岩石单轴抗压强度UCS和岩体完整性指标KV，分别建立UCS和KV关于TBM施工岩体质量4级分级的隶属度函数。采用单极性S形函数，分别构建UCS和KV的权重函数。这样，基于模糊数学的最大隶属度准则，就可以对TBM施工的岩体质量进行分级。同时，给出3个施工实例，演算表明，预测的结果与TBM施工实际相吻合，表明该分级方法简单而实用，具有很好的应用前景。

| Abstract: | According to tunnel boring machine(TBM) advance rate,surrounding rockmass is classified into 4 grades,i.e.good,comparatively good,comparatively bad and bad in working condition.Based on fuzzy mathematics method,two indices of uniaxial compressive strength UCS and rock mass integrity index KV are adopted;and their membership functions of the 4-grade classification of rock mass about TBM construction are established.Meanwhile,Sigmoid function is adopted to depict the weight of UCS and KV rather than a constan... |
