【摘要】：隨著我國經(jīng)濟的快速發(fā)展和持續(xù)增長，我國的公路建設(shè)也進入了前所未有的大發(fā)展時期。公路運輸事業(yè)也向著大噸位、高速度的方向發(fā)展。然而以半剛性基層為首選基層的公路項目，卻逐漸暴露出一些嚴重的缺陷。高速公路項目建設(shè)一次性投資大，特別是高速公路瀝青路面造價高昂，因此尋求有效的解決途徑來避免或減少公路半剛性基層的裂縫缺陷，并運用正確的成本分析方法對其進行經(jīng)濟分析，已成為高速公路建設(shè)項目穩(wěn)步發(fā)展的重要環(huán)節(jié)。 本文通過對玄武巖纖維半剛性基層的試驗數(shù)據(jù)的統(tǒng)計和分析，從技術(shù)上闡述了玄武巖纖維在公路半剛性基層的可行性以及使用中的理論最佳摻量。對半剛性基層在柔性路面體系的應(yīng)用及性能進行了分析，詳細闡述了黃驊港南疏浚港東延伸項目各路面方案，并根據(jù)國內(nèi)外路面使用性能周期研究成果和衰變模型選出適合黃驊港南疏浚港東延伸項目的預(yù)測模型，預(yù)測出不同方案下黃驊港南疏浚港東延伸項目公路路面使用性能的衰變規(guī)律和性能周期，為路面全壽命周期成本分析奠定基礎(chǔ)。通過運用全壽命周期成本分析理論，結(jié)合國內(nèi)外對于公路全壽命周期理論的研究成果，建立了高速公路全壽命周期成本計算模型，，進而應(yīng)用此模型對黃驊港南疏浚港東延伸項目建設(shè)方案進行經(jīng)濟分析。得到最終的結(jié)論：玄武巖纖維半剛性基層并未使得建設(shè)期投入成本增加，而且因為性能的提高降低了后期運營期內(nèi)養(yǎng)護成本和車輛運營成本。綜合考慮整個壽命周期，玄武巖纖維半剛性基層路面的成本最低，具有良好的經(jīng)濟性，推薦使用這種建設(shè)方案。 綜上，本文在借鑒國內(nèi)外已有的理論框架和工程實踐的基礎(chǔ)上，將全壽命周期成本理論應(yīng)用于減少路面裂縫發(fā)生的玄武巖纖維半剛性基層路面的經(jīng)濟分析上，全面考慮項目建造期、運營期直至報廢的全過程成本，對于形成一種追求項目一生所耗成本最小，使用效益最大的氛圍有利。
[Abstract]:With the rapid development and sustained growth of China's economy, China's highway construction has entered an unprecedented period of great development. Highway transportation also develops towards large tonnage and high speed. However, the highway project with semi-rigid base as the first choice gradually exposed some serious defects. Expressway project construction one-time investment is big, especially the highway asphalt pavement cost is high, therefore seeks the effective solution way to avoid or reduce the highway semi-rigid base course crack flaw, Using the correct cost analysis method to analyze its economy has become an important link in the steady development of highway construction project. Based on the statistics and analysis of the experimental data of basalt fiber semi-rigid base, the feasibility of basalt fiber in highway semi-rigid base and the optimum theoretical content in use are expounded in this paper. The application and performance of semi-rigid base course in flexible pavement system are analyzed, and the pavement schemes of the East extension Project of South dredged Port of Huanghua Port are described in detail. According to the research results of pavement performance cycle and decay model at home and abroad, the prediction model suitable for the East extension Project of South dredged Port of Huanghua Port is selected. The decay law and performance cycle of pavement performance of the East extension Project of South dredged Port of Huanghua Port under different schemes are predicted, which lays a foundation for the cost analysis of pavement life cycle. By applying the theory of life-cycle cost analysis and combining the research results of highway life-cycle theory at home and abroad, the calculation model of freeway life-cycle cost is established. Then the model is used to analyze the construction scheme of the East extension Project of South dredged Port in Huanghua Port. The final conclusion is that basalt fiber semi-rigid base does not increase the input cost in the construction period and the maintenance cost and the vehicle operation cost are reduced because of the improvement of the performance. Considering the whole life cycle, basalt fiber semi-rigid base pavement has the lowest cost and good economy. In summary, based on the existing theoretical framework and engineering practice at home and abroad, this paper applies the life-cycle cost theory to the economic analysis of basalt fiber semi-rigid base pavement which reduces the occurrence of pavement cracks. The overall consideration of the whole process cost of the project construction period, operation period and scrapping is beneficial to the formation of a kind of atmosphere in which the cost of pursuing the project is the least and the use benefit is the greatest.
