摘要
以国内外扁平大断面隧道断面型式、扁平率与支护参数的统计分析为基础,对依托深圳坪盐通道工程的马峦山隧道的设计参数进行了初步评估,得出结论:马峦山隧道设计的断面型式、扁平率及支护参数基本符合目前国内外大断面设计的趋势,总体上较为合理,但存在一定的优化空间。
Based on the statistical analysis of section type,flat rate and supporting parameter of the flat large-section tunnels at home and abroad,the article preliminarily evaluates the design parameters of Maluanshan Tunnel in Shenzhen-Pingshan-Yantian Expressway Project relying on Shenzhen-Pingshan-Yantian Expressway Project.The conclusion is that the design section type,flat rate and supporting parameters of Maluanshan Tunnel basically conform to the tendency of large-section design at home and abroad,are more reasonable as a whole,and but have the certain optimization space.
