【摘要】：山区高速互通立交设计是一项综合性强、难度大、涉及面广、影响因素多的复杂工作。虽然国内外互通立交都经历了数十年的发展阶段，互通立交设计理论也逐步建立和发展，但至今仍未成熟和完备，且仍较大程度地落后于高速公路的路线设计理论。山岭地区地形复杂，地面高差大，变化频繁，自然坡面陡，不良地质及特殊性岩土分布广泛，立交布设选型更显复杂，因此，继续探讨和研究山区互通立交设计理论是非常必要和迫切的。本文的研究内容是山区高速公路互通立交布设和选型多方案论证，是互通立交设计的核心内容。本文拟先整理、分析公路互通立交匝道的基础型式及特点，介绍公路互通立交的常用型式及适用条件；然后结合山区高速互通立交布设特点，从互通立交在路网中的功能、预测交通量、行车安全、地形符合性、全寿命周期成本、以人为本等方面提出山区高速公路互通立交选型的基本原则；接着归纳山区高速公路互通立交选型及比选论证的步骤和思路；最后，结合笔者实际工作中负责的粤东北及粤东两条山区高速互通立交工程设计实例，，从预测交通量及断面选择、互通型式初选、立交平纵设计、结构物布设及工程量统计、经济技术比选论证等方面进行展开，以通过实际山区高速互通设计应用进一步分析和总结山区高速互通立交选型及方案比选论证的方法和思路。通过本文的研究，希望可以对山区高速公路互通立交设计选型理论进一步拓展，为以后的设计工作起到指导作用。
[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.
