2) four lane road tunnel
四车道公路隧道
1.
With the rapid development of tunnel construction in China, the four lane road tunnel emerged in recent years.
我国的交通隧道建设事业发展迅速 ,近年来 ,出现了四车道公路隧道。
3) single-arch four-lane road tunnel
单拱四车道公路隧道
1.
The span-ratio of single-arch four-lane road tunnel is less than two or three lanes tunnel s greatly if technology and economic factors are taken into consider.
解决这个问题的办法就是修建多车道隧道，并且使隧道的宽度与隧道以外的道路宽度一致，这就提出了单拱四车道公路隧道的建设问题。
2.
In order to solve this problem effectively, large-span tunnel, for instance, single-arch four-lane road tunnel is constructed.
随着经济的快速发展,公路交通量猛烈增加,单个的小断面隧道已无法满足公路交通的需要,解决这个问题的方法之一就是修建多车道的大断面公路隧道,如:单拱四车道公路隧道。
3.
Due to the super-span,flat section shape and complex construction method of single-arch four-lane road tunnel,the stress distribution is non-uniform,and stress concentration appears in arch foot during construction,which leads to instability or even collapse of the surrounding rock.
单拱四车道公路隧道由于跨度特大、断面形状扁平、施工方法复杂,造成其在施工过程中应力分布不均匀,拱脚应力集中,从而极易导致围岩发生失稳乃至坍塌。
4) four-lane highway
四道公路
5) a four-lane highway
四线道公路
6) two-lane highway
双车道公路
1.
In order to research overtaking behavior on two-lane highways,the returnable time headway and the overtakable time headway were defined and their critical gap values were attained according to overtaking experiment.
为了研究双车道公路上的超车行为,定义了可回车车头时距与可超车车头时距,通过超车试验得到了两者的临界间隙值;分析了单向、双向车道的最小通行能力,合理解释了双向车道通行能力值小于2倍单向车道通行能力值的原因;最后确定了中国双车道公路上跟车车头时距值和跟车率。
2.
On the basis of substantive investigation and data collection which includes the data of the highway and traffic and accident,the quantitative influence of the accesses on the safety of two-lane highways is analyzed.
在对大量的双车道公路进行了调研和采集了海量的公路、交通、事故数据基础上,针对接入口对双车道公路交通安全的影响进行了量化分析。
3.
Furthermore,the criterion to evaluate two-lane highway alignment consistency was brought forward,referring to that of foreign countries and that of freeways in China.
针对公路线形连续是保证汽车安全行驶的基本要求,以运行车速为中介,提出了相邻路段运行车速相协调的路线设计理念,并参考国外双车道公路及国内高等级公路线形连续性评价标准,提出了双车道公路线形连续性评价标准。
