【摘要】：隨著吉林省經(jīng)濟(jì)的高速發(fā)展,汽車保有量大幅上升,高速公路的交通量逐年攀升,部分路段的峰值車流量已經(jīng)接近甚至超出了當(dāng)初的設(shè)計(jì)容量。吉林省位于東北平原中部,冬夏溫差高達(dá)60攝氏度,惡劣的氣候嚴(yán)重影響公路的使用壽命,伴隨著大量的車輛通行,吉林省高速公路病害頻繁發(fā)生。目前,吉林省高速公路管理部門面臨著,養(yǎng)護(hù)資金不足,檢測(cè)裝備匱乏,檢測(cè)手段落后,公路病害不能及時(shí)發(fā)現(xiàn),道路維修時(shí)不得不封閉公路等諸多問題。本文在吉林省高速公路管理局的項(xiàng)目“高速公路病害無損檢測(cè)的技術(shù)研究”的支撐下,提出了利用閑置的車輛,采購部分檢測(cè)部件,組裝一種低成本的簡(jiǎn)易路面路基病害同步檢測(cè)車的想法。通過對(duì)同一病害圖片進(jìn)行特征分析,分別使用三種濾波方式進(jìn)行圖片降噪處理,經(jīng)過對(duì)比選擇了平穩(wěn)小波閾值去噪算法作為路面病害圖像的濾波處理方式；結(jié)合吉林省高速公路路基病害的實(shí)際情況,確定了采用探地雷達(dá)作為路基病害的檢驗(yàn)工具。在簡(jiǎn)易檢測(cè)車組裝完成之后,在長(zhǎng)吉高速K0-K40路段做了實(shí)際測(cè)試,通過與高級(jí)多功能檢測(cè)車進(jìn)行路面路基病害對(duì)比試驗(yàn),獲得了準(zhǔn)確的測(cè)量數(shù)據(jù)。證明了簡(jiǎn)易檢測(cè)車在路面路基病害檢測(cè)兩方面,都能夠達(dá)到吉林省高速公路管理部門的實(shí)際生產(chǎn)要求,驗(yàn)證了利用閑置的車輛,采購部分檢測(cè)部件,組裝簡(jiǎn)易檢測(cè)車對(duì)路面路基病害進(jìn)行同步檢測(cè)是完全可行的。并對(duì)簡(jiǎn)易檢測(cè)車的應(yīng)用前景做了展望,說明了如果該設(shè)備能夠得到普及應(yīng)用,不僅能夠帶來巨大的經(jīng)濟(jì)效益,還能夠帶來良好的社會(huì)效益,具有一定的推廣價(jià)值。
[Abstract]:With the rapid development of economy in Jilin Province, the number of vehicles has increased greatly, and the traffic volume of expressway has increased year by year. The peak traffic volume of some sections of the highway has approached or even exceeded the original design capacity. Jilin Province is located in the middle of Northeast Plain, the temperature difference in winter and summer is as high as 60 degrees Celsius, the bad climate seriously affects the service life of highway, with a large number of vehicles passing through, highway diseases occur frequently in Jilin Province. At present, the highway management department in Jilin Province is faced with many problems, such as insufficient maintenance funds, lack of testing equipment, backward detection means, untimely detection of highway diseases, and closure of roads while maintaining roads. Supported by the project of Jilin Provincial Expressway Administration "Technical Research on Non-destructive Detection of Expressway Diseases", this paper puts forward the use of idle vehicles to purchase some testing parts. The idea of assembling a low-cost synchronous detection vehicle for pavement subgrade diseases. Through the feature analysis of the same disease image, three kinds of filtering methods are used to reduce the image noise, and the stationary wavelet threshold denoising algorithm is chosen as the filtering processing method of the road disease image. According to the actual condition of highway roadbed disease in Jilin province, the ground penetrating radar is adopted as the inspection tool of roadbed disease. After the assembly of the simple detection vehicle was completed, the actual test was made in the K0-K40 section of Changji Expressway, and the accurate measurement data were obtained by comparing the test with the advanced multi-function detection vehicle for pavement subgrade diseases. It is proved that the simple detection vehicle can meet the actual production requirements of the highway management department in Jilin Province in both aspects of pavement subgrade disease detection, and verify the use of idle vehicles to purchase some testing parts. It is feasible to assemble a simple detection vehicle to detect pavement subgrade diseases synchronously. The application prospect of simple inspection vehicle is prospected, and it is shown that if the equipment can be popularized and applied, it will not only bring great economic benefit, but also bring good social benefit, and it has certain popularization value.
