【摘要】：我國(guó)高海拔寒冷地區(qū)分布廣泛，這些地區(qū)氣候惡劣、地形地貌條件特殊、生態(tài)系統(tǒng)脆弱，而且社會(huì)、政治環(huán)境復(fù)雜，給公路建設(shè)工作提出了更高要求。目前針對(duì)高寒環(huán)境公路建設(shè)的研究多集中在微觀技術(shù)層面，忽視了宏觀層面上對(duì)設(shè)計(jì)思想和總體理念的研究，傳統(tǒng)以工程為主體的設(shè)計(jì)、施工、管理理念與技術(shù)體系也已經(jīng)無(wú)法應(yīng)對(duì)高寒地區(qū)資源、環(huán)境與工程建設(shè)之間日趨加深的矛盾。為實(shí)現(xiàn)高海拔寒冷地區(qū)公路建設(shè)的可持續(xù)發(fā)展，，從前期設(shè)計(jì)階段準(zhǔn)確把握工程建設(shè)的總體思路，全面開(kāi)創(chuàng)特殊氣候、自然地質(zhì)、地貌等條件下的公路設(shè)計(jì)理念創(chuàng)新與應(yīng)用迫在眉睫。 論文在系統(tǒng)分析國(guó)內(nèi)外相關(guān)研究成果的基礎(chǔ)上，通過(guò)資料收集與現(xiàn)場(chǎng)調(diào)查，歸納總結(jié)了高海拔寒冷地區(qū)主要自然環(huán)境特征以及社會(huì)、經(jīng)濟(jì)環(huán)境特征�？紤]高海拔寒冷環(huán)境下公路建設(shè)特殊需求，從交通安全事故多發(fā)、交融威脅工程質(zhì)量、低溫缺氧影響人身健康、路域生態(tài)環(huán)保困難、地質(zhì)條件復(fù)雜、隧道導(dǎo)致能源消耗巨大等方面詳細(xì)闡述了高海拔寒冷地區(qū)公路勘察設(shè)計(jì)面臨的特殊任務(wù)和難點(diǎn)，進(jìn)而明確了傳統(tǒng)公路設(shè)計(jì)理念在高海拔寒冷地區(qū)的適用性。針對(duì)高海拔寒冷地公路勘察設(shè)計(jì)的突出特點(diǎn)，秉承“六個(gè)堅(jiān)持，六個(gè)樹(shù)立”，開(kāi)展面向高海拔寒冷地區(qū)公路個(gè)性的設(shè)計(jì)新理念研究，圍繞“以安全為核心，以功能為導(dǎo)向，以人為本，動(dòng)態(tài)設(shè)計(jì)，節(jié)約資源，保護(hù)與改善環(huán)境”的總體思路，從系統(tǒng)工程思維的角度闡述了新理念的具體內(nèi)涵。最后，論文以丹拉國(guó)道西過(guò)境高速公路為依托，將提出的新理念具體應(yīng)用到路線走廊帶選擇、局部方案比選、橋隧設(shè)計(jì)、邊坡防護(hù)等設(shè)計(jì)實(shí)踐中，指導(dǎo)了西過(guò)境高速公路的路線選擇與設(shè)計(jì)，驗(yàn)證了研究成果的可行性。 高海拔寒冷地區(qū)公路設(shè)計(jì)新理念研究采用調(diào)查收集、理論分析、工程驗(yàn)證相結(jié)合的研究方法，研究成果彌補(bǔ)了我國(guó)現(xiàn)行公路設(shè)計(jì)理念對(duì)高寒環(huán)境考慮不足的缺陷，完善了現(xiàn)有公路設(shè)計(jì)理論體系，不僅對(duì)高海拔寒冷地區(qū)公路建設(shè)具有重要的實(shí)踐意義，而且對(duì)進(jìn)一步推進(jìn)我國(guó)交通事業(yè)的科學(xué)發(fā)展有著重要的理論意義。
[Abstract]:The cold regions with high altitude are widely distributed in China. These areas have bad climate, special topography and landform conditions, fragile ecosystem, and complicated social and political environment, which put forward higher requirements for highway construction. At present, the research on highway construction in the alpine environment is mostly focused on the micro technical level, neglecting the research on the design thought and the overall idea at the macro level, and the traditional design and construction with engineering as the main body. The management idea and technology system can not cope with the contradiction between the resources, environment and engineering construction. In order to realize the sustainable development of highway construction in the cold area of high altitude, the general idea of engineering construction is accurately grasped from the early stage of design, and the special climate and natural geology are created in an all-round way. It is urgent to innovate and apply the highway design idea under the condition of geomorphology. On the basis of systematic analysis of related research results at home and abroad, this paper summarizes the main natural environment characteristics, social and economic environment characteristics of cold areas at high altitude through data collection and field investigation. Considering the special needs of highway construction in the cold environment at high altitude, from traffic safety accidents, blending threatening engineering quality, low temperature and hypoxia affecting human health, difficult ecological environmental protection and complex geological conditions, In this paper, the special tasks and difficulties of highway survey and design in high altitude cold area are expounded in detail from the aspects of energy consumption caused by tunnel, and the applicability of traditional highway design concept in high altitude cold area is clarified. In view of the prominent characteristics of highway investigation and design in high altitude and cold region, we carry out the research on the new concept of highway personality design oriented to the high altitude cold area by adhering to "six persistence, six building", and focusing on "taking safety as the core and function as the guide," The general idea of people-oriented, dynamic design, saving resources, protecting and improving the environment is discussed, and the concrete connotation of the new idea is expounded from the point of view of system engineering thinking. Finally, based on the West Transit Expressway of Danla National Road, the paper applies the new idea to the design practice of route corridor belt selection, partial scheme selection, bridge and tunnel design, slope protection, etc. It guides the route selection and design of the west transit expressway, and verifies the feasibility of the research results. The research on the new concept of highway design in the cold area of high altitude adopts the research method of the combination of investigation collection, theoretical analysis and engineering verification, and the research results make up for the deficiency of the current highway design concept of our country considering the alpine environment. It not only has important practical significance for highway construction in cold areas at high altitude, but also has important theoretical significance to further promote the scientific development of transportation in our country.
