试坡主要是在已标出“控制点”的纵断面图上，根据技术和标准，选线意图，考虑各经济点和控制点的要求以及地形变化情况，初步定出纵坡设计线的工作。试坡的要点，可归纳为“前面照顾，以点定线，反复比较，以线交点”几句话。
前后照顾就是说要前后坡段统盘考虑，不能只局限于某一段坡段上。以点定线就是按照纵面技术标准的要求，满足“控制点”，参考“经济点”，初步定出坡度线，然后用三角板推平行线的办法，移动坡度线，反复试坡，对各种可能的坡度线方案进行比较，最后确定既符合标准，又保证控制点要求，而且土石方量最省的坡度线，将其延长交出变坡点初步位置。

結果 (英文) 1:

Try marked slope mainly in "control points" on the Profile, based on technologies and standards, alignment with intent, taking into account the economic points and control points, as well as the terrain changes, longitudinal design line that the initial period of work. Test points can be summed up as "front to take care of, to point to the line, repeatedly compared to line intersection," a few words.Slope before and after before and after care that is holistic consideration cannot be limited to a certain period on the slopes. To points set line is according to longitudinal surface technology standard of requirements, meet "points", reference "economic points", preliminary set out slope line, then with triangle Board push parallel of approach, mobile slope line, repeatedly try slope, on various may of slope line programme for compared, last determine both meet standard, and guarantee points requirements, and earthwork volume most province of slope line, will its extended surrendered variable slope points preliminary location.

結果 (英文) 2:

Test slope has been marked mainly in the "control points" in profile view, and according to the technical standard, line selection intent, requirements and consider changes in various economic terrain points and control points, preliminary design Longitudinal Line fix work . Important test slope, can be summarized as "front care to point alignment, repeated comparisons to the intersection of the line," a few words.
Before and after care before and after the slope that is to consider reunification segment, not just confined to a section of the slope section. Point alignment is in accordance with the vertical face technical standards, to meet the "control point" reference "economic point", the initial fix grade line, and then push the triangle parallel line approach, moving slope line, repeated the test slope, each possible to compare the slope of the line program, finalized in line with standards and requirements to ensure the control point, and the slope of the line cuts and fills most of the province, it will extend its initial position to surrender PVI.

結果 (英文) 3:

Test slope is mainly in the marked "profile control points", and according to the technical standard, the intention of route selection, considering the economic points and control points and terrain, initially set longitudinal slope design work line. Test points of the main points can be summarized as "in front of care, to point the line, repeated comparison, with the line intersection" a few words.That is to take care of before and after the slope before and after the round consideration, can not be confined to a certain slope section. To the point of alignment is in accordance with longisectional technical standards, to meet the "control point", "economic reference point", initially set the slope line, then use triangle push parallel line method, moving line of slope, slope test repeatedly, to compare the grade line of all kinds of alternatives, and finally determine the standard again, ensure the control requirements, and the province of earthwork slope line, extend the initial slope position change over.
