【摘要】：随着沥青路面在公路中的普遍应用,沥青路面在使用过程中也会有各种不同的破坏现象,因此沥青路面的养护已经成为各个公路养护站工作的重要组成部分,其经济投入比重也在逐渐增加。巴南区位于重庆市主城南部,属于九区之一,地处长江南岸丘陵地带,地址地貌形态多样,其国省县道的沥青路面在重庆这座山地城市也是具有代表性的。因此,对巴南区国省县道沥青路面年度养护数据的研究结果同样适用于重庆市的国省县道的沥青路面养护工程。规模.经济出现于成.本理论中,设计的是产.出与成.本的关系,即规模.经济与规模.不经济所要说明的是产出规.模扩大与成本变化之间的关系。规模.经.济实质由于生产.规.模扩大而导致长期平均成.本降低的情况。反之,规.模不经济是指由于生产.规.模扩大而导致长期平均成.本上升的情况[1]。在沥青路面养护工程中引入规模效益理论,可以在沥青路面养护工作中事半功倍,也就是所谓的“花最少的钱,做最多的事”。在技术.水平和其他投.入保持不.变的条件下,连续追.加一种生.产要素的投.入量,总是存.在着一个临.界点,超过这一点之后,再继续增加该要素的投入,所能得到增加的产出量是递减的。也就是说,当某种投入生产要素使用量达到一定点时,其边际量为零,因而往后再继续增加投入,不但不能使总产量增加,反而还会是总产量下降。这种现象称为边际效益递减规律。本文根据巴南区绍沥青路面的主要病害类型以及其主要维护方法,通过对巴南区国省县道沥青路面年度养护情况进行分析,把规模效益模型运用到沥青路面的养护工作中,对沥青路面养护的成本和规模进行了进一步的优化,通过对不同里程的沥青路面的养护成本进行对比分析,得到一个最优养护规模所在的区间。
[Abstract]:With the widespread application of asphalt pavement in highway, asphalt pavement will also have a variety of damage phenomena in the process of use, so the maintenance of asphalt pavement has become an important part of the work of various highway maintenance stations. The proportion of its economic investment is also gradually increasing. Bannan is located in the south of Chongqing's main city, belonging to one of the nine regions, located in the hilly region of the southern bank of the Yangtze River, with various address landforms. The asphalt pavement of its provincial and county roads is also representative in Chongqing, a mountainous city. The results of the research on the annual maintenance data of asphalt pavement of county road in Banan are also applicable to the asphalt pavement maintenance project of county road in Chongqing. The scale and economy appear in Cheng. In this theory, the relationship between production, production and production. That is, scale, economy and scale. What is not economical is the relationship between output specification, model expansion and cost change. Regulation. Mould diseconomy means that the long-term average result is caused by the expansion of production. [1]. Introducing the theory of economies of scale in asphalt pavement maintenance works can achieve twice the result with half the effort in the maintenance of asphalt pavement. That is, the so-called "spend the least money, do the most things". Under the condition that technology, level, and other investments remain unchanged, continuously pursue and add a kind of input and input of birth and output elements, always at a point near the boundary. Beyond this point, and then continue to increase the input of this element, the increase in output is decreasing. That is, when a certain input factor is used at a certain point, its margin is zero. Therefore, if we continue to increase investment in the future, we will not be able to increase the total output. This phenomenon is called the law of diminishing marginal benefit. In this paper, according to the main disease types of asphalt pavement in Banan and its main maintenance methods, Based on the analysis of the annual maintenance of asphalt pavement, the scale benefit model is applied to the maintenance of asphalt pavement, and the cost and scale of asphalt pavement maintenance are further optimized. By comparing and analyzing the maintenance cost of asphalt pavement with different mileage, the optimal maintenance scale is obtained.
