【摘要】：隨著國家西部大開發(fā)戰(zhàn)略的深入實(shí)施，西部地區(qū)高速公路發(fā)展迅猛，但受地形、地質(zhì)條件及投資的限制，西部山區(qū)高速公路線形平、縱、橫指標(biāo)受到約束，道路設(shè)計(jì)指標(biāo)偏低，多為連續(xù)坡道和急彎等彎坡組合路段，交通事故隱患較多且后續(xù)救援困難，因而造成的后果往往較為嚴(yán)重。為減少山區(qū)高速公路交通事故，提高道路行車安全性，本文對如何提高已建高速公路長大縱坡路段行車安全性的工程方案問題進(jìn)行了深入研究，主要內(nèi)容包括道路安全性評價(jià)理論探討、安全強(qiáng)化工程方案研究、工程實(shí)施效果分析等。 論文首先從剖析交通系統(tǒng)“人、車、路、環(huán)境”四要素與交通事故的關(guān)系入手，結(jié)合西漢高速澇峪段道路條件及事故原因分析，研究其交通事故形成機(jī)理，有針對性地選取了設(shè)計(jì)符合性、運(yùn)行速度協(xié)調(diào)性、設(shè)計(jì)速度與運(yùn)行速度協(xié)調(diào)性、車輛彎道行駛穩(wěn)定性和車輛制動效能熱衰退性等作為安全性評價(jià)指標(biāo)體系，對西漢高速澇峪段道路安全性進(jìn)行評價(jià)。在此基礎(chǔ)上，結(jié)合西漢高速澇峪段道路條件及安全設(shè)施現(xiàn)狀，從研究相關(guān)安全設(shè)施的功能及作用入手，遵循針對性、系統(tǒng)性和配套性原則，重點(diǎn)從限制運(yùn)行速度、保證剎車制動系統(tǒng)性能、制動失效后的避險(xiǎn)措施、改善防撞效果等角度，提出了強(qiáng)化安全檢查區(qū)及臨時停車區(qū)、緊急停車帶、避險(xiǎn)車道、防撞護(hù)欄及標(biāo)志標(biāo)線、機(jī)電工程等交通安全強(qiáng)化方案設(shè)計(jì)。根據(jù)西漢高速澇峪段安全強(qiáng)化工程實(shí)施情況，對各強(qiáng)化方案的實(shí)施效果進(jìn)行定性分析，引入國民經(jīng)濟(jì)評價(jià)采用的“有無對比法”，對其進(jìn)行經(jīng)濟(jì)費(fèi)用效益定量測算，并強(qiáng)調(diào)了加強(qiáng)安全設(shè)施的管理、超載的管理、提高駕駛員安全意識等措施對保證安全強(qiáng)化工程實(shí)施效果的重要性。
[Abstract]:With the further implementation of the strategy of developing the western region of China, the expressway in the western region is developing rapidly. However, due to the constraints of topography, geological conditions and investment, the alignment, vertical and horizontal indexes of the expressway in the western mountainous area are restricted, and the road design index is on the low side. Most of them are composed of continuous ramps and sharp bends and so on. There are many hidden dangers of traffic accidents and difficulties in subsequent rescue, so the consequences are often more serious. In order to reduce the traffic accidents and improve the safety of the highway in mountainous area, this paper makes a deep research on how to improve the driving safety of the long longitudinal slope section of the existing expressway. The main contents include the evaluation theory of road safety, the research of safety strengthening project, the analysis of the effect of project implementation, etc. This paper begins with the analysis of the relationship between the four elements of traffic system "people, cars, roads and environment" and traffic accidents, and analyzes the road conditions and accident causes of the high-speed waterlogging section of the Western Han Dynasty, and studies the formation mechanism of the traffic accidents. The safety evaluation index system is selected such as design conformance, running speed coordination, design speed and running speed harmony, vehicle bend driving stability and vehicle braking efficiency thermal degradation. The safety of the high speed waterlogging section of the Western Han Dynasty was evaluated. On this basis, combined with the road conditions and the present situation of the safety facilities in the West Han high-speed waterlogging section, the paper starts with the study of the function and function of the relevant safety facilities, follows the principles of pertinence, systematization and supporting, and focuses on limiting the speed of operation. From the angles of ensuring the performance of braking system, avoiding danger after braking failure, improving the effect of collision prevention and so on, this paper puts forward the strengthening of safety inspection area and temporary parking area, emergency stop belt, safe lane, collision barrier and marking line, etc. Mechanical and electrical engineering and other traffic safety strengthening scheme design. According to the implementation of the safety strengthening project in the high speed waterlogging valley section of the Western Han Dynasty, the effect of each strengthening scheme is qualitatively analyzed, and the comparative method of national economic evaluation is introduced to measure the economic cost benefit quantitatively. It also emphasizes the importance of strengthening the management of safety facilities, overloading management and raising the safety consciousness of drivers in order to ensure the effect of safety strengthening engineering.
