摘要: 西安地裂缝是一种地区性的地质灾害现象。目前西安共发育有14条地裂缝。地铁四号线将穿越13条,给隧道施工造成了诸多考验。文章选取西安市地铁四号线沿线的地裂缝灾害作为研究对象。探讨了地裂缝对隧道工程的影响因素和致灾特点、以及相关的评估理论方法。最后针对地裂缝灾害特征以及工程特点提出若干防治措施,对于科学研究地裂缝的灾害特点、合理防治地裂缝的灾害发生具有一定的指导意义。Abstract: Xi'an ground fissure is a regional geological disaster,which is growing 14 ground fissures.Xi'an subway line 4 will passing through 13 ground fissures,causing many tests in tunnel construction.The author selects ground fissures along Xi'an subway line 4 as the study object,then discusses the factors affected to tunnel projects and hazard characteristics,finally puts forward many countermeasure to hazards of ground fissures aiming at engineering characteristics.The results have important directive to study characteristics of ground fissures scientifically and control them.
