【摘要】:當前,四川省普通國道正由以建為主向建養(yǎng)并重轉(zhuǎn)變,社會發(fā)展對公路養(yǎng)護工作的要求越來越高,但普通國道養(yǎng)護管理、決策方法等并未實質(zhì)性響應(yīng)發(fā)展要求,影響普通國道服務(wù)能力的提升。四川省普通國道在養(yǎng)護資金極其有限的前提下,養(yǎng)護資金緊缺和資金使用結(jié)構(gòu)不合理問題并存。養(yǎng)護內(nèi)容正從單純的強度要求過渡到路面技術(shù)狀況的全方位要求,養(yǎng)護決策需要從定性分析向定量分析發(fā)展,運用科學的方法進行預養(yǎng)護,放大養(yǎng)護資金作用,提高四川省普通國道路況水平。本文擬通過文獻研究和實地調(diào)查,收集基礎(chǔ)數(shù)據(jù),分析四川省普通國道主要病害類型及成因,對影響路況的內(nèi)外因素進行統(tǒng)計分析,通過回歸分析構(gòu)建四川省普通國道柔性面層技術(shù)狀況預測模型。通過不同時段路面預養(yǎng)護的效益比較,確定最佳養(yǎng)護時機,并針對公路具體病害選擇預養(yǎng)護措施。首先,通過實地考查,收集基礎(chǔ)數(shù)據(jù),對四川省普通國道主要病害及成因進行分析歸納。其次,在孫立軍教授柔性面層技術(shù)狀況預測模型的基礎(chǔ)上,以G108四川段為例,通過對歷年路面技術(shù)狀況檢測數(shù)據(jù)的回歸分析,構(gòu)建按照交通量及路面結(jié)構(gòu)層厚度分類的四川省普通國道柔性面層技術(shù)狀況(PCI、RQI)預測模型。然后,在四川省普通國道柔性面層技術(shù)狀況預測模型中加入一個路面預養(yǎng)護回歸系數(shù),將不同時間點的柔性面層預養(yǎng)護所對應(yīng)養(yǎng)護效益進行比較,確定最佳柔性面層預養(yǎng)護時機。最后,對傳統(tǒng)養(yǎng)護措施進行整合,結(jié)合柔性面層預養(yǎng)護新方法和四川省普通國道實際,針對裂縫類、松散類、變形類等不同的病害提出灌縫、微表處、薄層罩面等柔性面層預養(yǎng)護措施。
[Abstract]:At present, Sichuan province is a common highway construction to the construction and maintenance of social transformation, development of highway maintenance work demands more and more high, but ordinary highway maintenance management, decision making method has not substantive response requirement of the development of ordinary highway service capacity. The premise of the general national highway in Sichuan province is extremely limited in maintenance funds next, the shortage of maintenance fund and the use of capital structure unreasonable problems coexist. The full range of requirements of maintenance content from a simple transition to the technical condition of pavement strength requirements, maintenance decision-making needs from qualitative analysis to quantitative analysis, the use of scientific methods to conduct preventive maintenance, maintenance funds amplification effect, improve road traffic level in Sichuan province. This article, through literature research and field investigation, collecting basic data, analysis of the causes and types of diseases in the general national highway in Sichuan Province, due to the impact of road conditions on the inside and outside In statistical analysis, through regression analysis, the construction of Sichuan Province ordinary highway flexible surface condition prediction model. Through the different periods of pavement preventive maintenance efficiency, determine the optimal maintenance time, and for the choice of preventive maintenance measures of highway concrete disease. Firstly, through on-the-spot investigation, collect the basic data of main diseases and causes of common highway in Sichuan province were analyzed and summarized. Secondly, based on the prediction model of technical condition of Professor Sun Lijun flexible surface on the G108 section of Sichuan as an example, through the test data on the technical condition of the road over the regression analysis, constructed according to the technical condition of Sichuan Province ordinary State Road traffic volume and flexible pavement thickness (PCI, layer classification RQI) prediction model. Then, the technical condition of the general national highway in Sichuan province flexible surface prediction join a pavement preventive maintenance model of regression coefficient, will not be at the same time, the soft The surface layer of the corresponding pre maintenance maintenance benefits compared to determine the optimal flexible surface pre maintenance time. Finally, the integration of the traditional conservation measures, combined with the flexible pavement maintenance and new method of pre Sichuan Province ordinary state road, to crack, loose, not with the disease such as the deformation of crack filling, micro at the table, face flexible surface pre curing measures cover sheet.
