摘　　要：西安南京铁路东秦岭特长隧道全长 12 2 6 8m ,设计为双线加平行导坑方案 ,钻爆法施工。隧道进出口各 35m采用模筑混凝土衬砌 ,洞身其余地段采用复合式衬砌 ,支护均以喷、锚、网为主 ,并辅以钢架。隧道设计总工期为 5 8.32个月 ,是全线的控制性工程。从地质特征、方案比选。East Qinling Super-long Tunnel has a total length of 12,268m. According to design, the twin-track tunnel with parallel heading shall be excavated using drill and blast method. Form concrete lining shall be applied to the sections 35m to entrance and exit, and composite lining shall be applied to the remaining part. Shotcreting, anchor bolts and wire mesh are principal supporting means assisted with steel frame. The tunnel is the control project of Xi'an-Nanjing Railway, and is scheduled to be completed in 58.32 months. Design program of the tunnel is illustrated from geological characteristics, selection of program, and structural design, etc.
