(1) a hard time preparations
Plot line and mark the height of pile in, confirm the position of the pile in. Information collection and become familiar with the specifications.
(2) where the callout control points
Locus of control refers to the influence of road longitudinal slope design of elevation points. Such as route, destination, key bridges and culverts, adverse geological sections of the minimum fill, maximum digging depth, main buildings along the roads, intersections and other factors limit the elevation of the road through the control points, and so on.
(3) test
Try slope mainly in the already marked "control points" Profile based on the intentions of technical indicators and line selection, combined with the up and down, in a "control point" basis, taking into account the majority of "economic" principle, in interludes between those points and cut-off straightened, try to set aside a certain straight slope line. To compare all possible straight line again, elect conforms to the technical standards, and meet point requirements and early earthwork design lines in the province as straight lines, straight slope line extension, set the initial position of grade change.
(4) adjustments
After the trial, will be set by the longitudinal line longitudinal to consider when comparing both should meet. If there is a difference, it should conduct a comprehensive analysis to find out the causes, checked against the specification and design of maximum longitudinal slope, slope gradient and slope length of synthesis and so on whether met regulatory requirements, coordination of horizontal alignment and vertical alignment the desirability and so on.
(5) check
According to the adjusted straight slope line, select the cross section of key controls, such as the high fill retaining wall in deep excavation, and an important bridge and culvert sections, read out the corresponding directly to the Profile in the piles of fill (dig) height and check for cut and fill, slope foot fall to the ground or retaining the.
(6)
After adjustment check that can be set. Are piecewise straight lines of slope gradient, grade change point position (number) and elevations determined. General to adjust the grade change point to 5M or 10m on the whole, change of elevation based on longitudinal slopes, slope lengths in turn calculated to determine.
(7) the longitudinal design results as shown in table 1

（1）辛苦准备
情节线和标志桩的高度，确认桩的位置。信息收集和熟悉的规格。
（2）凡标注控制点
控制源指的高程点道路纵坡设计的影响。如路线，目的地，键桥涵，最小的不利地质螺纹部分，最大挖掘深度，沿着道路，交叉路口等的因素主要建筑物限制道路的标高通过控制点，等等。
（3）测试
试坡主要是基于配置文件的技术指标和选线的意图已经标有“控制点”，结合上下，在“控制点”的基础上，考虑到“经济”原则的大多数，在那些截点和拉直之间穿插，尽量留出某些斜率直线。要再次比较所有可能的直线，符合技术标准ELECT，并满足点要求和年初土方的线条设计在全省为直线，直线的斜率延伸，集品位变化的初始位置。
（4）调整
庭审结束后，将由纵线设置时需要考虑的纵向比较，两者不应该满足。如果是有区别的，它不应该进行全面的分析，找出原因，核对规格和最大纵坡，坡度和坡长合成的设计等无论监管要求得到满足，水平对齐方式和垂直对齐的可取性等协调。
（5）检查
根据调整后的直线斜率线，选择关键控制，如在深基坑开挖高丝挡土墙，一个重要的桥梁和涵洞段的横截面，读出直接对应于成堆的档案纱（DIG）高度的时间并为切纱，坡脚或掉在地上保留了。
（6）
调整检查后可以是集。确定坡度，高档点的变化位置（号）和海拔的分段直线。一般以调整等级变化点为5M或10米整体上，基于纵坡海拔的变化，进而计算斜坡长度确定。
