摘　　要：以瓦日铁路太岳山隧道泥岩为研究对象,通过干燥饱和吸水率试验和干燥饱和崩解试验,分析干燥崩解物粒径分布特征、耐崩解性,从崩解物粒度特征的角度反映岩石的膨胀性,对二叠系膨胀岩判别和耐崩解性评价进行补充,并根据华北二叠系泥岩的特点,提出隧道设计及施工的建议。Based on Taiyueshan tunnel mudstone of Watang-Rizhao Railway as the research object,this paper analyzed and discussed the distribution characteristics of dry crumbling particle size and its slaking durability through the dry saturated water absorption and dry saturated disintegration tests. In addition,it made a supplement to discrimination of Permian swelling rock and evaluation of slaking durability from the perspective of crumbling granularity characteristics to reflect the expansion of the rock,and put forward suggestions for the tunnel design and construction according to the characteristics of the Permian mudstone in North China.
