钻爆法公路隧道成套标准图服务
收藏资源简介:
通过构建适用于在不同公路等级、设计速度条件下的各类钻爆法隧道结构标准图,公路等级包括高速公路、一级公路、二级公路,设计速度涵盖120km/h、100km/h、80km/h和60km/h,横断面尺寸分为标准断面和与路基同宽断面,布置形式分为普通分离式、小净距和连拱,实现公路隧道的标准化设计,帮助勘察设计单位提高设计效率,为参建单位提供数据支撑服务。
By developing standard drawings for various drill-and-blast tunnel structures applicable to different highway grades and design speeds—where highway grades include expressways, first-class highways and second-class highways, and design speeds cover 120km/h, 100km/h, 80km/h and 60km/h. The cross-sectional dimensions are categorized into standard sections and sections matching the width of the highway subgrade, while the layout forms are divided into three types: ordinary separated tunnels, small clear-distance tunnels and twin-arch tunnels. This work achieves standardized design of highway tunnels, enhances design efficiency for survey and design institutes, and offers data support services for all participating construction units.
