摘要

太行山隧道是以特殊性岩体Ⅴ级角砾状泥灰岩（膏溶角砾岩）为主的客运专线隧道，通过对这一特殊岩体隧道的监控量测，掌握了隧道在开挖中的变形及周边位移发展机理和围岩压力的变化规律，优化施工和支护参数,并可用以指导类似工程的设计和施工。

Abstract

Taihangshan tunnel is a passengerdedicated railway tunnel located dominantly in breccia marl of Grade Ⅴ ground (gypsum breccia). By means of monitoring on the tunnel located in the special ground, the mechanisms of the deformation and displacement of the tunnel and the variation rule of the rock mass pressure are obtained to optimize the tunnel construction and the reinforcement parameters. The paper can provide reference for the design and construction of similar works in the future.

Key words： gypsum breccia tunnel excavation ; deformation analysis ; rock pressure
