摘　　要：中缅油气管道澜沧江桥隧工程由"一桥两隧"组成,穿跨越位置地形起伏剧烈,气象、地质条件极为复杂,下游新建水电站蓄水形成库岸再造,使得管道穿跨越工程设计难度极大。经过多方案勘察、比选,确定了"地质选线、以桥定隧,桥隧结合"的设计理念,并充分利用现场各种可以利用的条件,使管道顺利通过澜沧江。梳理了该工程设计的7大难点,描述了穿越断面选择及穿跨越工程设计的过程和思路,可以为大口径管道通过类似地区及特殊难度穿跨越工程设计提供借鉴。Lantsang bridge and tunnel crossing project for the Myanmar-China Oil and Gas Pipeline consists of one bridge and two tunnels. Because of the serious landform relief and complex meteorological and geological conditions at crossing location, and the reservoir bank rebuilding as a result of water storage for a new hydropower station downstream, the project design is extremely diffi cult. After survey and comparison of multiple programs, the following design philosophy is determined, that is, line selection according to geological conditions, tunnel excavation based on bridge, and coexistence of bridge and tunnel. Moreover, all available site conditions will be considered to make the pipeline pass the Lantsang successfully. This paper presents seven diffi culties of the design, and describes the process and approach of the selection of crossing section and the design of crossing project. The results can provide a reference to the design of large-diameter pipelines crossing similar or specifi c areas.
