摘要

本段公路地处吉林省东南部自然风景秀丽的长白山西侧，属化夏系第二隆起带，由起点向东地形起伏逐渐加大，沿线所经地区沟谷发育，河谷及台地多为水田及旱田，山地多为天然次生林及小面积人工林。沿线以旱田为主，在黄泥河流域内有部分水田。沿线除越岭山地为灌木林及次生林外，余均为季节性农作物。

根据本路在公路网中的作用和交通量，结合本路的功能，性质几自然状况，公路等级确定为二级公路标准，全线采用双车道，计算行车速度60km/小时。

路线线形设计，尽量与实际地形，地貌及周围景观相协调，线形连续，指标均衡，视线诱导好，在工程量增加不大的情况下尽可能采用较高的指标，力求纵横配合，线形流畅。

路线设计起点里程桩号为K0+000终点里程桩号为K2+215.592，全线长2..215公里，路线主要经过重丘区。本标段设了4个圆管涵和2个小桥梁。路基宽度采用10米，路面宽度采用2x3.5米，硬路肩采用2x0.75米，土路肩采用2x0.75米，行车道横坡度设为1.5%，路肩横坡度设为3%。为了顺利的将路基范围内的路面水排出，在路堑两侧设置了边沟。

路面设计根据公路等级，以及该路在公路网中的作用，且依据沿线材料种类、数量、质量按照BZZ—100重型标准轴载，采用沥青混凝土路面，路面结构层厚度由路面结构图标明。

本设计中采用了CAD2004道路软件，较好的完成了道路的平、纵、横设计及路基土方、占地等的计算，大大提高了工作效率。

Abstract

this section of roads are situated at southeast Jilin Province west side natural scenery beautiful Changbai Mountain, is the summer is the second upheaval zone, enlarges gradually by the beginning to the east hypsography, passes through the local run-off ditch growth along the route, the river valley and the terrace many for the paddy field and the dry farmland, the mountainous region many for the natural secondary forest and the small area planted forest. By the dry farmland primarily, has a part of paddy field along the route in the Huangni River basin. Besides more range mountainous region is along the route the scrub forest and the secondary forest, Yu Junwei seasonal crops.

According to this road's in highway network function and the volume of traffic, unifies this road's function, nature several natural conditions, the highway classification determination for the second-class road standard, uses the two-lane on all fronts, the computation running speed 60km/hour.

The route geometric design, as far as possible with the actual terrain, the landform and periphery the landscape is coordinated, linear continuously, the target is balanced, the line of sight induces, in the resilience increases in not the big situation to use the high target as far as possible, makes every effort vertically and horizontally to coordinate, linear smooth.

The location beginning course station number is the K0+000 end point course station number is K2+215.592, the entire line long 2..215 kilometers, the route mainly passes through Zhongqiu District. This sign Duan She 4 circular pipes have contained with 2 small bridges. The roadbed width uses 10 meters, the surface width uses the 2x3.5 rice, the hard road shoulder uses the 2x1.75 rice, the unprotected shoulder uses the 2x0.75 rice, the lane transverse grade supposes is 1.5%, the shoulder slope supposes is 3%. For smooth discharges the roadbed scope's in road surface water, was cutting the both sides to establish the side ditch.

Pavement design basis highway classification, as well as this road's in highway network function, and rests on along the route the material category, quantity, the quality according to the BZZ-100 heavy standard axle load, uses the asphalt coagulation earthen road pavement, pavement structure level thickness marks by the road surface structure drawing.

In this design has used the CAD2004 path software, good has completed the path even, vertical, the horizontal design and the roadbed folk recipe, the occupying land area and so on computation, raised the working efficiency greatly.
