基于可拓理论的围岩稳定分类方法的研究

Research on methods of surrounding rock masses stability classification based on extension theory

在双护盾TBM(tunnel boring machine)的隧洞施工中,将可拓理论与洞室围岩稳定评价相结合.基于碴料和掘进参数的地质编录所提供的地质信息,选取了能够反映围岩稳定综合特性的评价指标,确定围岩稳定类型和预测前方岩体情况.在物元理论、可拓集合论和关联函数运算的基础上,建立了隧洞围岩稳定分类的可拓评价方法,其中引进了隶属度的概念和一种定量的指标权重的确定方法,并在山西引黄工程的双护盾TBM隧洞施工中用此分类方法对某两段围岩进行了稳定分类,得到的稳定分类结果与实际情况吻合.
