摘　　要：基于神延线黄土隧道塌方实例,用统计方法,并通过理论分析,初步揭示了黄土微地质构造对黄土围岩稳定的影响方式及造成黄土隧道塌方的作用机理,分析并掌握黄土微地质构造对黄围岩稳定的影响和方式及造成黄土隧道塌方的作用机理,对于黄土隧道塌方预报及黄土隧道施工的防灾、减灾有积极意义,在工程实践中也取得了很好的效果。Loess--due to the special geological history, reasons resulting in being, chemical composing and ingredient of grain, geological disasters as eoUapse in eonstruetion of loess tunnel happens frequently. The author revealed the way in prineipium that the miere-geologieal structure of loess action affects on the stability of loess tunnel surroundings and the action mechanism resulting in collapse of loess tunnel, therefore that is laying an significance on recognition and mastery of the way and action mechanism for disasters prevention and minimization. It also plays well in actual practice.
