沿道路中线竖直剖切再行展开即为路线纵断面。它反映了道路中线地面高低起伏

沿道路中线竖直剖切再行展开即为路线纵断面。它反映了道路中线地面高低起伏的情况及设计路线的纵向坡度情况，从而可以看出纵向土石方工程的挖填情况。把道路的纵断面图与平面图结合起来就能完整的表达出道路的空间位置。纵断面设计的主要内容是根据道路等级、沿线自然条件和构造物控制标高等，确定路线合适的标高、各坡段的纵坡度和坡长，并设计竖曲线。

結果 (英文) 1:

Along the center line vertical cutting line is the route profile. It reflects the ups and downs road ground in the middle of the situation and design of vertical slope, so that you can see the vertical earthwork digging and filling. The road Profile combined with plans to complete the express road location. Vertical section design of main content is based on road grade, along the natural conditions and high structure control, confirm the right elevation, the longitudinal slope gradient and slope length and design of vertical curves.

結果 (英文) 2:

Vertical cut along the middle road is re-expand the route profile. It reflects the situation of road longitudinal slope midline undulating ground conditions and design line, which can be seen in the case of longitudinal cut and fill earthwork project. The profile view and a plan view of the road will be able to combine the complete expression of the spatial position of the road. The main content profile design is based on road grade, natural conditions and structures along the elevation control, etc., to determine the appropriate course of elevation, slope length and grade each of longitudinal slope section, and vertical curve design.

結果 (英文) 3:

Along the line of the middle line of the vertical section and then expand the line is a vertical section. It reflects the longitudinal slope condition and design route of road line ups and downs of the ground, it can be seen that the vertical earthwork dig fill. By combining the longitudinal section of the road with the plan, the space position of the road can be expressed completely. The main content of longitudinal section design is according to the road grade, the natural condition and the structure control standard, to determine the appropriate level of the road, the slope and slope length of the slope, and the design of vertical curve.
