【摘要】：国道丹东至阿勒泰公路洛古河至黑蒙界段是洛古河与内蒙古间唯一的公路,旧路为砂石路面,路基宽5.0米-6.5米,全线均为天然形成的大车道,春季路段翻浆、病害严重,夏季晴天通车一路灰尘、雨天一路泥泞或干脆断行,冬季路面滑且窄,纵坡起伏较大,事故频繁发生,给居民出行造成了不便,也制约了两省间文化交流、区域经济和旅游业等发展。尤其是近几年,随着两省经济的发展,交通量及其荷载增长较快,使得原本运营状况较差的该段公路破损日趋严重,已经无法适应目前的交通运输需要。因此,本项目的实施对内蒙古与大兴安岭地区之间的运输通道,完善公路网的配置,满足对交通需求的增长,进一步扩大交通运输干线的辐射范围,促进相互之间的经济发展具有重大意义。本文首先采用OD调查法和断面交通量观测法对现有交通量进行调查分析,运用“弹性系数法”预测本路段未来20年的交通流量,指导下一步的方案设计。其次,充分考虑该路段建设条件和影响建设的其他因素,着重分析旧路现状及病害原因,在尽量使用旧路的前提下设计工程方案。再次,对本项目建设期和运营期采用经济净现值(ENPV)、经济效益比(EBCR)、经济投资回收期(N)和经济内部收益率(EIRR)四项指标进行国民经济评价,完成投资估算,预测经济效益,并根据估算费用和交通量可能变化的幅度进行敏感性分析。最后,将在充分利用旧路的前提下分析占用土地情况及合理估算补偿费用；严格按照“三同时”要求分析工程建设对环境的影响,提出减缓工程环境影响的对策；采用“有此工程”情况和“无此工程”情况对比的方法对未来20年汽车燃油消耗量进行节能评价。根据上述调查分析、预测及评价的结果,论证该项目建设是否可行。
[Abstract]:The section between Luogu River and Haimeng on the Dandong to Aletai highway is the only highway between Luogu River and Inner Mongolia. The old road is a gravel road, the roadbed width is 5.0 meters to 6.5 meters, the whole line is a natural long lane, and the spring section is muddy and seriously diseased. Open to traffic and dust on sunny days in summer, muddy or simply cut off on rainy days, slippery and narrow roads in winter, large ups and downs of longitudinal slopes, frequent accidents, causing inconvenience to residents' travel and restricting cultural exchanges between the two provinces. Development of regional economy and tourism. Especially in recent years, with the economic development of the two provinces, the traffic volume and its load increase rapidly, which makes the damage of this section of the highway, which used to be poor, become more and more serious, and can not meet the current traffic and transportation needs. Therefore, the implementation of this project will improve the allocation of highway network, meet the growth of traffic demand, and further expand the radiation range of the main lines of traffic and transportation, for the transportation passage between Inner Mongolia and Daxing'anling region, to improve the allocation of the highway network, and to meet the growth of traffic demand. Promoting mutual economic development is of great significance. In this paper, OD survey method and cross-section traffic volume observation method are used to investigate and analyze the existing traffic volume, and the elastic coefficient method is used to predict the traffic flow in the next 20 years, which will guide the next project design. Secondly, considering the construction condition of the section and other factors affecting the construction, the paper analyzes the present situation of the old road and the cause of the disease, and designs the project scheme under the premise of using the old road as much as possible. Thirdly, the paper evaluates the national economy by using the economic net present value (ENPV), the economic benefit ratio (EBCR), the economic investment recovery period (N) and the economic internal rate of return (EIRR) in the construction and operation periods of the project, and completes the investment estimation and forecasts the economic benefits. Sensitivity analysis is also carried out according to the estimated cost and the extent of possible changes in traffic volume. Finally, under the premise of making full use of the old road, the situation of occupied land and the reasonable estimation of compensation cost will be analyzed, and the environmental impact of engineering construction will be analyzed strictly according to the requirements of "three simultaneous", and the countermeasures to mitigate the environmental impact of the project will be put forward. The method of comparing the situation of "with this project" and "without this project" is used to evaluate the energy saving of automobile fuel consumption in the next 20 years. According to the above investigation, forecast and evaluation results, the feasibility of the project is demonstrated.
