| 摘 要： | 针对甘肃省及临近地区干旱、半干旱黄土地区工程地质、水文地质特点，实地调查该地区已建隧道渗漏水情况，分析该地区隧道渗漏水成因。以天巉二级汽车专用公路9座隧道为依托，应用工程类比法提出适合该地区的涌水类型划分方法，涌水类型划分为滴渗、淋淌、股水和突水4种，并分析了影响隧道防排水结构设计的因素和防排水设计原则。在此基础上，提出了防排水设计的4种合理结构型式及其适用条件。研究结果为天巉公路、巉柳公路防排水设计与施工提供了有效指导。

| Abstract: | In light of the characters of engineering geology and hydrogeology in Gansu Province and near areas, influencing factors of the design for waterproof and drainage in road tunnel are analyzed; the topographical features, vegetation, construction method, leakage of groundwater of loess and weak surrounding rock of highway tunnel in the district are investigated. Cause of leakage in the tunnel is analyzed. On the basis of the natural conditions, field investigation of seepage and disaster conditions of road tunnel, classification of outflow types for highway tunnel is presented with analogical method. Based on nine tunnels in Tianshui to Chankou Highway, principle of design for waterproof and drainage in highway tunnels construction is provided. Based on above analysis, four reasonable structural styles and section configurations for design of waterproof and drainage are proposed. |
