摘要:
东非大裂谷火山?地震?断层移动和地裂缝等地质作用活跃,严重威胁隧道安全,有必要研究裂谷内山岭隧道地质灾害破坏?通过系统分析东非大裂谷山岭隧道地质灾害风险源,建立了 4类 22项风险评价指标体系以及裂谷内山岭隧道地质灾害风险熵权可拓物元方法评价方法,开发了相应的风险安全可视化程序,得到东非大裂谷山岭隧道地质灾害破坏等级,提出了相应风险控制措施?运用该模型得到东非大裂谷内马铁路 2号隧道地质灾害破坏等级为 S4,对此风险控制措施可为提高抗隧道震设防烈度,进行隧道抗断层?抗震和抵抗火山作用综合研究设计,严格把控隧道施工质量,进行裂谷地质活动和隧道安全监测,及时进行隧道地质灾害预警,同时制定隧道地质灾害处置和救援预案?研究结果可对类似工程地质灾害风险评价和控制研究提供参考?
Abstract:
The active geological processes of the Great Rift Valley of East Africa,such as volcanos,earthquakes,fault movement and ground fissures,seriously threaten the safety of mountain tunnels,so it is necessary to studythe geological disaster damage of mountain tunnels in the Great Rift Valley. This paper systematically analyzes therisk sources of geological disasters of mountain tunnel in the Great Rift Valley in East Africa,establishes the risk assessment index system with 4 categories-22 items and the entropy weight matter-element extension evaluation method for the geological disaster risk of the mountain tunnel in the Rift Valley,then develops the corresponding risk safety visualprogram,obtains the damage level of geological disasters of the tunnel in the Great Rift Valley in East Africa,and puts forward the corresponding risk control measures. The research results show that the damagelevel of geological disaster of tunnel No.2 of Malaysia railway in the Great Rift Valley is S4. The risk controlmeasures are suggested such as the improving of tunnel seismic fortification intensity,comprehensive design of tunnel for anti-fault,anti-seismic and anti-volcanic action,the strict control of tunnel construction quality,the early warning and monitoring of geological disasters in tunnels,and the tunnel geological disaster treatment andrescue. The research results of this paper can provide reference for similar engineering geological hazard riskassessment and control research.
