摘　　要：内昆线岩脚一号隧道位于一巨型岩堆体内,隧道在施工期间曾出现山体位移、开裂和下沉,洞内出现衬砌开裂和坍方冒顶。文章详细叙述了病害产生的原因和相应的处理措施,并采用有限元程序和条分法对整个岩堆体的稳定性进行了分析检算。Yanjiao No. 1 tunnel on Neikun railway is located at a rock block accumulation and mountain movement, crack, settlement, lining crack and collapse occurred during the tunnel construction. In this paper the causes and treatment measures to the tunnel disease are presented. Furthermore the stability of rock accumulation is analyzed and calculated by FEM method.
