结合三维地质模型对某公路隧道突泥灾害的原因分析和处置对策结合三维地质模型对某公路隧道突泥灾害的原因分析和处置对策 【摘要】公路隧道穿越区域变质作用下形成的混合岩（岩性接近花岗岩）区域，且当隧址接近构造带及其影响带时，因周边岩体风化程度较高、风化区域较深以及大气降水的影响，出现涌水突泥地质灾害的概率较高。本文基于广西壮族自治区的岑溪市境内某公路隧道的涌水突泥灾害现场资料的收集和调查，结合专业软件生成的三维地质模型，分析导致涌水突泥产生的原因，提出针对性的处置对策，最后对灾害成因的多方面原因思考进行总结并提出一些建设性的意见。 【关键词】公路隧道；混合岩；涌水突泥；三维地质模型；地质预报 【 abstract 】 highway tunnel through regional metamorphism mixture formed under rocks (lithology close to granite) area, and when the tunnel structure belt and its influence to the address with, because of the surrounding rock weathering degree is higher, weathering area was deep and precipitation, the influence of water gushing appeared at a higher probability of geological disaster in mud. This paper based on the guangxi zhuang autonomous region within the territory of the CenXi city expressway tunnel construction of water gushing tu mud disaster site investigation and collection of data, combined with the professional software of the generation of 3 d geological model and analyzes cause water gushing axon the causes of mud, and puts forward the countermeasure pertinence disposal, and finally to the cause of the disaster various reason thinking summarized and puts forward some constructive Suggestions. 【 key words 】 highway tunnel; Mixed rock; Water gushing tu mud; 3 d geological model; Geological forecast 中图分类号： U45 文献标识码：A 文章编号 1 引言 1.1 隧道概况 该隧道位于广西岑溪市境内，为避开占用耕地和房屋，路线沿重丘山区的狭长走廊带边缘分布，至隧址区需穿越相对高差 200m 的山体，大致呈北（进口）南（出口）走向...
