摘　　要：并排的纵剖面上采用斜(竖)井布置的隧洞,通常采用的完全平行的布置型式,但当水头较高时,往往有以下缺点:如两洞间施工支洞封堵稳定无法满足、封堵工期紧张、下斜井检查与维修困难等问题。采用斜(竖)井错落布置,可以有效的解决以上问题,可在并排布置的隧洞设计中参考采用,具有很好推广和借鉴意义。The tunnels with shaft(inclined shaft) at abreast longitudinal section are often arranged fully parallel layout type.But with the higher water head,it has disadvantages as follow,unsatisfied plugging stability of construction adit between two tunnels,shorter plugging construction time,difficult checking and maintenance entering into the inclined shaft,etc.The staggered layout of shaft(inclined shaft) could effectively solve the above troubles,and provides reference for design of tunnel with abreast layout.
