| 摘 要： | 岩爆是深埋隧洞开挖中主要工程问题之一，如何对其进行准确预测也是岩石工程的重点研究课题。针对深埋隧洞围岩发生岩爆的随机性和模糊性，将岩爆视为一种风险，引入以可靠度为基础的模糊概率风险理论，建立了一个新的岩爆风险预测模型——模糊概率风险分析模型，该方法克服传统判别方法的不足，既能预测岩爆的发生，又能计算各级岩爆发生概率。结合工程常用的Russenes岩爆判别法，推导出模型的概率密度函数和隶属函数形式。应用该方法对南水北调西线工程泥曲-杜柯河段隧洞部分洞段进行岩爆风险评估，并与常规岩爆判别法对比。

| Abstract: | Rockburst is one of the most important problem during the excavation of deep-buried tunnels.How to predict rockburst accurately is one of the major subjects in geotechnical engineering.With the randomness and implicit vagueness of rockburst in deep-buried tunnels,rockburst can be considered as a risk.Fuzzy probability risk theory based on reliability is introduced to evaluate rockburst risk,a new rockburst risk prediction model of fuzzy probability risk analysis is established.This method overcomes the disa... |
