摘要
针对甘肃黄土区的自然条件,依据该地区已建黄土及软岩公路隧道渗漏水调查情况和铁路隧道涌水状态分类,运用工程类比法提出适合该地区公路隧道防排水结构设计的隧道涌水类型划分及对涌水类型校核与细分的三种方法。隧道涌水类型划分对该地区中短隧道涌水预测极为方便,为甘肃省天巉二级汽车专用公路设计与施工提供了有效指导。
In view of the natural conditions in loess area of Gansu, in the light of investigation conditions of seepage of built loess and weak rock highway tunnels in this area and classification of water gushing eonditions for railway tunnels, and by engineering analogism, the elassifieation of tunnel water gushing types suited the structure design of highway tunnel waterproof and drainage, and the three methods for checking and subdividing water gushing types are presented. This elassification is exeeedingly convenient to pre-estimate the medium short runnel gushing in this area, which provided an effective guide for the design and construction of Tianchan 2 grade special purpose highway in Gansu province.
