【摘要】：根據(jù)吉林省高速公路網(wǎng)發(fā)展規(guī)劃,到2030年,全面建成吉林省高速公路網(wǎng),高速公路通車里程達到5000公里,除長白縣、臨江市外,全省所有的縣、市、區(qū)基本通高速公路,一般汽車在1小時以內(nèi)可進入高速公路網(wǎng),山區(qū)高速公路建設(shè)數(shù)量將持續(xù)大量增加。由于山區(qū)地形地質(zhì)條件復雜,路堤高填深挖和隧道工程將不可避免。路塹和隧道開挖產(chǎn)生大量石質(zhì)棄渣且山區(qū)缺乏優(yōu)良的土質(zhì)填料,因此合理利用石質(zhì)棄渣進行山區(qū)高等級公路路堤填筑是非常必要的。本文針對填石路堤的粒料規(guī)格與攤鋪層厚及壓實參數(shù)相互關(guān)系的研究、填石路堤攤鋪、碾壓工藝和質(zhì)量控制、路堤壓實度檢測方法及整體強度穩(wěn)定性和沉降機理技術(shù)分析。通過現(xiàn)場實驗及理論分析等綜合研究,最終提出合理的施工關(guān)鍵技術(shù)要求,并制定填石路堤的壓實標準和檢測方法。填石路堤穩(wěn)定性與沉降機理的研究,有利于進一步完善和提高我國公路填石路堤施工技術(shù),提高公路修筑技術(shù)水平,可以為山嶺區(qū)公路建設(shè)過程中的填石路堤施工控制提供依據(jù)和指導,應用范圍廣闊。填石路堤填筑技術(shù)的應用,可充分利用挖方材料,從而能夠大量節(jié)約公路建設(shè)資金,并保護沿線環(huán)境,這符合經(jīng)濟建設(shè)有效、健康的發(fā)展目標,有著十分重大的經(jīng)濟和社會意義。
[Abstract]:According to the development plan of the highway network of Jilin Province, by 2030, the highway network of Jilin Province will be completed in an all-round way, and the mileage of the expressway will reach 5000 kilometers. All counties, cities, and districts in the province, except Changbai County and Linjiang City, will have access to the highway. As cars can enter the highway network within one hour, the number of highway construction in mountainous areas will continue to increase substantially, because of the complex terrain and geological conditions in mountainous areas. High fill and deep excavation of embankments and tunnel works will be inevitable. Cutting and tunnel excavation will produce a large amount of stone debris and the mountain areas lack of good soil fill. Therefore, it is very necessary to make use of stone slag to fill the embankment of high grade highway in mountainous area. This paper studies the relationship between the grain material specification of the embankment and the thickness of the paving layer and compaction parameters, and the paving of the embankment. Roller compaction technology and quality control, compaction testing method of embankment, overall strength, stability and settlement mechanism of embankment are analyzed. Through comprehensive research of field experiment and theoretical analysis, the reasonable key technical requirements of construction are put forward. The study on the stability and settlement mechanism of the rockfill embankment is beneficial to the further improvement and improvement of the construction technology of the rockfill embankment in China, and to the improvement of the technical level of the highway construction. It can provide the basis and guidance for the construction control of rockfill embankment in mountain area. The application of rockfill embankment filling technology can make full use of excavating materials, so as to save a lot of highway construction funds. And protect the environment along the line, which accords with the economic construction effective, healthy development goal, has the very important economic and social significance.
