施工隧道岩爆风险安全预警

Safety Warning of Rock Burst Risk in the Constructing Tunnel

在国内外典型隧道岩爆案例的基础上,总结了岩爆发生规律,提取了岩爆主要影响因素,基于模糊理论建立了岩爆事故的概率及规模综合评价模型,并将模型应用于西南地区某隧道中,验证了多级模糊综合评价模型在岩爆预警中的有效性。

This paper bases on the typical cases of rock burst at home and abroad,summarizes the occurrence regularity of rock burst,determines the main influencing factors of rock burst,establishes the probability and loss comprehensive evaluation model of rock burst on the basis of fuzzy theory,which is applied to the tunnel in the southwest in China,and verify the effectiveness of the multilevel fuzzy comprehensive evaluation model in security safe warning of rock burst.
