【摘要】：山區(qū)高速互通立交設(shè)計(jì)是一項(xiàng)綜合性強(qiáng)、難度大、涉及面廣、影響因素多的復(fù)雜工作。雖然國內(nèi)外互通立交都經(jīng)歷了數(shù)十年的發(fā)展階段，互通立交設(shè)計(jì)理論也逐步建立和發(fā)展，但至今仍未成熟和完備，且仍較大程度地落后于高速公路的路線設(shè)計(jì)理論。山嶺地區(qū)地形復(fù)雜，地面高差大，變化頻繁，自然坡面陡，不良地質(zhì)及特殊性巖土分布廣泛，立交布設(shè)選型更顯復(fù)雜，因此，繼續(xù)探討和研究山區(qū)互通立交設(shè)計(jì)理論是非常必要和迫切的。本文的研究內(nèi)容是山區(qū)高速公路互通立交布設(shè)和選型多方案論證，是互通立交設(shè)計(jì)的核心內(nèi)容。 本文擬先整理、分析公路互通立交匝道的基礎(chǔ)型式及特點(diǎn)，介紹公路互通立交的常用型式及適用條件；然后結(jié)合山區(qū)高速互通立交布設(shè)特點(diǎn)，從互通立交在路網(wǎng)中的功能、預(yù)測交通量、行車安全、地形符合性、全壽命周期成本、以人為本等方面提出山區(qū)高速公路互通立交選型的基本原則；接著歸納山區(qū)高速公路互通立交選型及比選論證的步驟和思路；最后，結(jié)合筆者實(shí)際工作中負(fù)責(zé)的粵東北及粵東兩條山區(qū)高速互通立交工程設(shè)計(jì)實(shí)例，，從預(yù)測交通量及斷面選擇、互通型式初選、立交平縱設(shè)計(jì)、結(jié)構(gòu)物布設(shè)及工程量統(tǒng)計(jì)、經(jīng)濟(jì)技術(shù)比選論證等方面進(jìn)行展開，以通過實(shí)際山區(qū)高速互通設(shè)計(jì)應(yīng)用進(jìn)一步分析和總結(jié)山區(qū)高速互通立交選型及方案比選論證的方法和思路。通過本文的研究，希望可以對山區(qū)高速公路互通立交設(shè)計(jì)選型理論進(jìn)一步拓展，為以后的設(shè)計(jì)工作起到指導(dǎo)作用。
[Abstract]:The design of high speed interchange in mountainous area is a complex work with strong comprehensiveness, difficulty, wide coverage and many influencing factors. Although the interchanges at home and abroad have undergone decades of development and the interchange design theory has been gradually established and developed, it is still not mature and complete, and still lags behind the highway route design theory to a large extent. The terrain in the mountain area is complex, the ground height difference is large, the change is frequent, the natural slope is steep, the bad geology and particularity rock and soil are widely distributed, and the arrangement and selection of the interchange is more complicated. It is necessary and urgent to continue to study the design theory of mountain interchange. The research content of this paper is the multi-scheme demonstration of interchange arrangement and type selection of expressway interchange in mountain area, and is the core content of interchange design. In this paper, the basic types and characteristics of highway interchange ramp are analyzed, and the common types and applicable conditions of highway interchange are introduced, and then the function of interchange in the road network is analyzed according to the layout characteristics of high speed interchange in mountainous area. The basic principles of expressway interchange selection in mountainous area are put forward in the aspects of traffic volume, traffic safety, terrain conformance, life-cycle cost and people-oriented. Then the paper sums up the steps and ideas of the type selection and comparison of expressway interchange in mountainous areas. Finally, combining with the design examples of the two mountain high speed interchange projects in northeast Guangdong and eastern Guangdong, which are in charge of the author's practical work, From the aspects of traffic volume prediction and section selection, primary selection of interchange types, horizontal and longitudinal design of interchange, structure layout and engineering volume statistics, economic and technical comparison and demonstration, etc., Through the practical design and application of high speed interworking in mountainous area, the paper further analyzes and summarizes the method and train of thought of the selection and demonstration of the type selection and scheme comparison of high speed interchange in mountainous area. Through the research of this paper, it is hoped that it can further expand the theory of design and selection of expressway interchange in mountain area, and play a guiding role in the future design work.
