【摘要】：道路排水問題常常導(dǎo)致路面損壞、行車安全及路基水毀等一系列災(zāi)害的產(chǎn)生,其對(duì)路基危害的主要表現(xiàn)為排水形式不當(dāng)引起的坡面沖刷和邊坡失穩(wěn)等�？梢娧芯柯访媾潘问胶推旅娣雷o(hù)對(duì)于減小公路路基水損害,保障路基安全運(yùn)營(yíng)具有重要意義。目前,國(guó)內(nèi)外學(xué)者已對(duì)路面排水和坡面防護(hù)開展了較多的研究,但公路排水系統(tǒng)的形式和設(shè)計(jì)方法多直接套用現(xiàn)有規(guī)范或國(guó)內(nèi)外標(biāo)準(zhǔn),邊坡防護(hù)的設(shè)計(jì)通常獨(dú)立于公路排水系統(tǒng)之外,失去了邊坡防護(hù)與排水系統(tǒng)的統(tǒng)一性。針對(duì)上述問題,本文依托已國(guó)家高速公路網(wǎng)嵐曹高速臨棗段路面排水改造工程,重點(diǎn)對(duì)高速公路路面排水進(jìn)行系統(tǒng)分析。本文通過分析路面結(jié)構(gòu)水損壞機(jī)理、路面排水系統(tǒng)的組成、路面分散式排水和路面集中排水機(jī)理,總結(jié)了不同路面排水形式的適用條件；通過理論計(jì)算和FLAC3D數(shù)值模擬的手段,分別計(jì)算了路基坡面沖刷穩(wěn)定性和路基邊坡整體穩(wěn)定性,對(duì)路基的坡面防護(hù)形式和臨界地下水位高度進(jìn)行了相應(yīng)的計(jì)算；分析了分散式排水改集中排水的可行性并進(jìn)行了設(shè)計(jì)計(jì)算；最后提出了路面排水系統(tǒng)及邊坡防護(hù)綜合設(shè)計(jì)方法,并就具體改造工程設(shè)計(jì)了具體的施工方案。本文研究成果通過補(bǔ)充和完善高速公路排水系統(tǒng)及防護(hù)的計(jì)算和設(shè)計(jì)理論,使公路排水和防護(hù)趨于合理,提高了高速公路抗水毀能力和整體穩(wěn)定性,對(duì)于保障高速公路的長(zhǎng)期安全運(yùn)營(yíng)具有重要意義。
[Abstract]:Road drainage problems often lead to a series of disasters, such as road surface damage, driving safety and subgrade water damage. The main hazards to roadbed are slope erosion and slope instability caused by improper drainage form.It can be seen that the study of pavement drainage and slope protection is of great significance to reduce the road subgrade water damage and ensure the safe operation of roadbed.At present, scholars at home and abroad have carried out more research on pavement drainage and slope protection, but the forms and design methods of highway drainage system are mostly directly applied to existing codes or standards at home and abroad.The design of slope protection is usually independent of highway drainage system, which loses the unity of slope protection and drainage system.In view of the above problems, this paper focuses on the systematic analysis of highway surface drainage by relying on the road surface drainage reconstruction project of Lancao Expressway in Lancao Expressway.Through analyzing the mechanism of water damage of pavement structure, the composition of pavement drainage system, the mechanism of pavement dispersion drainage and the mechanism of road surface concentrated drainage, this paper summarizes the applicable conditions of different pavement drainage forms, and by means of theoretical calculation and FLAC3D numerical simulation,The erosion stability of embankment slope and the overall stability of embankment slope are calculated respectively.The feasibility and design calculation of decentralized drainage for centralized drainage are analyzed. Finally, a comprehensive design method for pavement drainage system and slope protection is put forward, and a concrete construction scheme is designed for the concrete reconstruction project.By supplementing and perfecting the calculation and design theory of highway drainage system and protection, the research results of this paper make the highway drainage and protection more reasonable, and improve the anti-damage ability and overall stability of freeway.It is of great significance to ensure the long-term safe operation of expressway.
