【摘要】:近十年來(lái),湖南省乃至全國(guó)的高速公路建設(shè)事業(yè)均取得了舉世曙目的成績(jī)。高速公路通車?yán)锍痰募眲≡黾?使得高速公路路面的養(yǎng)護(hù)問(wèn)題顯得越來(lái)越重要。就湖南省而言,可以預(yù)計(jì)在“十二五”末,其高速公路事業(yè)將進(jìn)入建設(shè)與養(yǎng)護(hù)并舉,且逐步以養(yǎng)護(hù)為主的發(fā)展模式。然而在實(shí)際的路面養(yǎng)護(hù)工作中,普遍存在養(yǎng)護(hù)維修標(biāo)準(zhǔn)不統(tǒng)一、養(yǎng)護(hù)決策較隨意、養(yǎng)護(hù)效益不高等現(xiàn)象,且始終存在養(yǎng)護(hù)需求與養(yǎng)護(hù)資金缺乏的矛盾。在這種背景下,進(jìn)行高速公路路面養(yǎng)護(hù)決策及優(yōu)化研究,對(duì)維持并不斷改善路面技術(shù)狀況、延長(zhǎng)路面使用壽命及充分發(fā)揮路面養(yǎng)護(hù)資金的使用效益具有十分重要的意義。基于此,本文以瀝青混凝土路面為對(duì)象,結(jié)合湖南省高速公路路面養(yǎng)護(hù)決策工作的實(shí)際,進(jìn)行湖南省瀝青混凝土高速公路路面養(yǎng)護(hù)決策技術(shù)的研究。主要研究成果如下:(1)根據(jù)面層材料、結(jié)構(gòu)層組合形式及厚度的差異進(jìn)行了湖南省瀝青高速公路典型路面結(jié)構(gòu)形式的劃分,并基于對(duì)代表性瀝青路段歷年路面檢測(cè)數(shù)據(jù)的統(tǒng)計(jì)分析,確定了湖南省瀝青高速公路的路面損壞特征及路面使用性能變化規(guī)律。(2)通過(guò)分析湖南省高速公路現(xiàn)行的路面破損評(píng)價(jià)指標(biāo)的缺陷,且針對(duì)該省瀝青路面的損壞特點(diǎn),建立了一種瀝青路面破損狀況評(píng)價(jià)的新方法。并基于路面養(yǎng)護(hù)決策的需要,建立了以瀝青路面微觀性能指標(biāo)破損率及車轍深度為對(duì)象的時(shí)間序列預(yù)測(cè)模型。(3)緊密圍繞湖南省高速公路路面養(yǎng)護(hù)決策工作的核心內(nèi)容及問(wèn)題,運(yùn)用科學(xué)分分析方法與理論,建立了湖南省瀝青混凝土高速公路路面中修工程資金與路面性能指數(shù)的經(jīng)驗(yàn)關(guān)系式,有效輔助了高速公路管理部門進(jìn)行規(guī)劃年路網(wǎng)路面養(yǎng)護(hù)目標(biāo)的決策;基于方差最大化的組合賦權(quán)理論提出了項(xiàng)目級(jí)路面養(yǎng)護(hù)目標(biāo)確定方法,解決了網(wǎng)級(jí)路面養(yǎng)護(hù)目標(biāo)在項(xiàng)目級(jí)層次的分配問(wèn)題。另外,還研究了路面養(yǎng)護(hù)資金優(yōu)化分配的解決方法,建立了用于瀝青路面養(yǎng)護(hù)需求分析的決策樹(shù)模型,并基于效果費(fèi)用比排序理論提出了規(guī)劃年瀝青混凝土高速公路養(yǎng)護(hù)路段及養(yǎng)護(hù)對(duì)策的優(yōu)化模型。
[Abstract]:In the past ten years, Hunan province and even the whole country have made great achievements in highway construction. With the rapid increase of highway mileage, the maintenance of expressway pavement becomes more and more important. As far as Hunan Province is concerned, it can be predicted that at the end of the 12th Five-Year Plan, the expressway industry will enter the development mode of construction and maintenance, and gradually focus on maintenance. However, in the actual pavement maintenance work, the maintenance standard is not uniform, the maintenance decision is random, the maintenance benefit is not high, and there is always the contradiction between the maintenance demand and the maintenance fund. Under this background, it is of great significance to carry out the decision-making and optimization of expressway pavement maintenance to maintain and continuously improve the pavement technical condition, to prolong the pavement service life and to give full play to the utilization benefit of pavement maintenance funds. Based on this, this paper takes the asphalt concrete pavement as the object, combined with the actual situation of the highway pavement maintenance decision in Hunan Province, carries on the research of the asphalt concrete highway pavement maintenance decision-making technology of Hunan Province. The main research results are as follows: (1) according to the difference of surface layer material, structural layer combination form and thickness, the typical pavement structure form of Hunan asphalt expressway is divided. And based on the statistical analysis of the pavement detection data of representative asphalt sections over the years, The pavement damage characteristics and pavement performance changes of Hunan asphalt expressway are determined. (2) through analyzing the defects of the existing pavement damage evaluation index of Hunan Province highway, and aiming at the damage characteristics of the asphalt pavement in Hunan Province, A new method for evaluating the damage of asphalt pavement is established. And based on the needs of pavement maintenance decision-making, A time series prediction model of asphalt pavement micro-performance index damage rate and rutting depth is established. (3) the core contents and problems of highway maintenance decision-making work in Hunan Province are closely related. Based on the scientific analysis method and theory, the empirical relationship between the capital and pavement performance index of asphalt concrete expressway pavement in Hunan Province is established. Effectively assisted the highway management department to plan the annual road network and pavement maintenance objectives decision-making; Based on the combination weight theory of maximization of variance, this paper presents a method to determine the objective of pavement maintenance at project level, which solves the problem of assignment of maintenance objectives at project level. In addition, the solution of optimal allocation of pavement maintenance funds is studied, and a decision tree model for asphalt pavement maintenance needs analysis is established. The optimization model of asphalt concrete expressway maintenance section and maintenance countermeasures is proposed based on the effect cost ratio ranking theory.
