本次设计内容按照我系部道桥教研室所提供的广西区宜州至忻城的地形图纸上的选线。选线时，充分利用建设用地要求，尽量少取农田耕地，认真的勘察路线所经过路段的地质级水文条件，尽量保证路线、经济性和安全性的前提，减少投资。
路线走向基本 尽量避免让等高线高程相垂直，优先选择与等高线相平行。为了使线形和优美，在本次设计，采用回旋曲线、圆曲线长度，回旋曲线之 尽可能要求，比例1：1：1~1：2：1。平曲线与竖曲线设计时，满足组合平包竖的要求；最大合成坡度要求不得大于其9%，最小合成的坡度不得小于其0.5%，避免了急弯与陡坡重合的线形。除此要求之外，在以上条件允许的情况，尽量采用较高的技术标准，总之要保证使平纵线形顺适、合理、曲线条优美，不允许条件的情况，中线设计的平面，线形基本上在满足技术要求，经济指标前提下，考虑少占经济作物地、填挖平衡，此次拟订了两个方案：甲方案、乙方案，经过方案比选，甲方案定选为正选方案。

結果 (英文) 1:

Content in accordance with part I of this design for road and bridge Department of the Guangxi yizhou to xincheng topographic maps provided by selected lines on the paper. Selected lines, make full use of land for construction requirements, less farmland as possible, carefully survey the route level section of the geological and hydrological conditions, as possible routes, economy and safety of premises, reducing investment.Gao Chengxiang vertical routes to avoid contour lines, parallel with the contour of choice. In order for the linear and elegant, this design, using swing curves, curve length, circular curve requirements as much as possible, 1:1:1~1:2:1. Horizontal curves and vertical curve design, meet the requirements of combination packages for vertical; the largest synthetic slope requirements shall not be greater than the 9%, synthesis of minimum slope must not be smaller than the 0.5% to avoid sharp bends and steep slope overlapping alignment. Except this requirements zhiwai, in above conditions allows of situation, as used high of technology standard, anyway to guarantee makes flat longitudinal linear Shun suitable, and reasonable, and song line beautiful, not allows conditions of situation, Middle design of plane, linear basically in meet technology requirements, economic index premise Xia, consider less accounted for cash crops to, and fill dug balance, the developed has two a programme: party case, and b programme, after programme than selected, party case set selected for are selected programme.

The design elements Selection topographic drawings to Yizhou Guangxi Xincheng County Department of I Department of the Ministry BRIDGES provided on follow. When the line selection, make full use of land for construction requirements, try to take less of farmland, serious investigation route through which sections of the geological level hydrological conditions, try to ensure that the premise of course, the economy and security, reducing investment.
Directions to try to avoid basic elevation contour lines perpendicular to the preferred parallel with the contour lines. In order to make linear and graceful, in this design, clothoid, circular curve length, swirling curve of possible claims, the ratio of 1: 1: 1 to 1: 2: 1. Flat curve and vertical curve design to meet the combination of horizontal and vertical package requirements; maximum gradient synthesis claim is not greater than 9 percent, the smallest synthetic slope of not less than its 0.5% to avoid sharp bends and steep coincident linear. In addition beyond the requirements in the above conditions permit, as far as possible high technical standards, in short, to ensure that the level of vertical alignment along appropriate, reasonable, beautiful curves strip, circumstances do not permit conditions, the design of the midline plane, linear basic on meet the technical requirements under the premise of economic indicators, taking little account of economic crops, the cut and fill balance, the developed two programs: a program, option B, through the scheme comparison, preferably methyl program given positive alternatives.

Line selection in the design of the content provided in accordance with the Ministry of road and Bridge Department Department of Guangxi District of Yizhou to Xincheng terrain on drawings. Line selection, make full use of construction land, farmland to take seriously the route survey, geological and hydrological conditions of the road after class, try to ensure that the premise of the route, economy and safety, reduce investment.Route to the basic try to avoid the elevation of vertical lines, the first choice of parallel with the contour lines. In order to make the linear and graceful, in this design, the use of the convolution curve, the curve length, the curve of the required, as far as possible, the ratio of 1:1:1~1:2:1. The design of plane curve and vertical curve, to meet the requirements of vertical combination package; maximum slope is not greater than the minimum requirement of 9%, the synthesis of slope shall not be less than the 0.5%, to avoid sharp bends and steep slopes of linear superposition. In addition to this requirement, the above conditions permit, as far as possible the use of technical standards in higher, to ensure that the horizontal and vertical alignment, a beautiful curve, reasonable accommodation, do not allow conditions, lines of plane design, in line basically meet the technical requirements of economic indicators under the premise of considering less economic crops to cut and fill balance, the formulation of the two plan: a plan, plan B, after the program selection, a scheme is chosen as positive solution.
