摘　　要：洞门是一座隧道的重要组成部分。其结构形式多样。选用时应根据洞口地形、地质条件以及工程特点而定。本文结合京沪高速铁路隧道门设计的要求及特点 ,详细介绍了一种新颖的洞门结构形式——无端墙隧道门的结构特点、适用条件、排水系统及结构检算。The tunnel portal is an important part of a tunnel. They are multiformed, and should be selected according to their topographic and geologic conditions and their working trait. Combined with the design requirements and the trait of the tunnel portal at Beijing Shanghai high speed railway, this paper introduces a new type of tunnel portal——the tunnel portal without end wall. Its trait, adopted conditions, drainage system and account of structure are introduced in detail.
