1) large span section
大跨断面
2) large cross section tunnel
特大断面大跨隧道
1.
The large cross section tunnel had been constructed more and more for its beautiful line type and high utilization ratio.
特大断面大跨隧道因其空间利用率高、线形美观，适应目前高速公路发展的总趋势，因而其工程实践不断增多。
2.
The twin sidewall drift method has been adopted to construct large cross section tunnel when the rock mass is bad.
随着断面跨度的不断增大,公路隧道设计开挖方式也在不断转变,目前在破碎围岩段,特大断面大跨隧道较多地采用双侧壁导坑法。
3) long-span roof
大跨度屋面
1.
Interpolation method for the calculation of wind pressure distributions on long-span roofs;
大跨度屋面风压分布的插值计算方法
2.
Due to the airflow separation and re-attachment,wind pressure distribution on long-span roofs is complicated.
风流经大跨度屋面结构时会产生复杂的气流分离及再附着 ,因而大跨度屋盖表面的风压分布较为复杂 ,从迎风前缘区域到尾部的风压变化梯度很大 ,这使得仅仅采用一个体型系数很难反映屋面的风荷载 。
