【摘要】：在經(jīng)濟發(fā)展的強勢帶動下，國內(nèi)的交通事業(yè)也在迅猛向西部山區(qū)推進，然而山區(qū)的地形地貌、氣候環(huán)境、交通需求、城鎮(zhèn)分布等與東部地區(qū)有很大差異，特別是互通式立交占地面積大，與山區(qū)用地條件復(fù)雜的矛盾尤為突出。目前山區(qū)高速公路在進行立交建設(shè)時，仍然是在直接套用東部的設(shè)計方法，未能結(jié)合山區(qū)高速公路建設(shè)的特點，既破壞了周圍的自然環(huán)境，又給工程建設(shè)帶來了較大的浪費。 本論文研究的目的是為山區(qū)復(fù)雜環(huán)境條件下，修建互通式立交提供新思路。在總結(jié)國內(nèi)外文獻的基礎(chǔ)上，首先分析了山區(qū)高速公路和互通式立交的特點以及山區(qū)互通式立交選型的影響因素，將在山區(qū)布置互通式立交的限制條件分為兩類：高差限制和平面限制，并提出了立交平面影響區(qū)域，除了互通式立交用地范圍，還分析了互通式立交與立交、隧道、服務(wù)設(shè)施、收費站間的合理距離。通過總結(jié)山區(qū)互通式立交的限制條件，提出了變異立交的概念，并以常規(guī)形式的互通式立交為基礎(chǔ)，通過理論分析并結(jié)合在實際工程中應(yīng)用的變異立交形式，，將變異立交按位置劃分為：常規(guī)形式分離變異立交、連接線變異立交、匝道變異立交和變異組合式立交。在此分類的基礎(chǔ)上，由常規(guī)形式匝道、變異匝道及連接線進行自由組合，得到了多種變異立交形式。從駕駛習(xí)慣、構(gòu)造物層數(shù)、山區(qū)限制條件等考慮，推選出33種變異立交形式，并通過詳細(xì)分析每種變異立交形式的特點，明確了各種變異立交形式的適用性，開拓了山區(qū)復(fù)雜環(huán)境下的互通式立交設(shè)計思路，為推進西部山區(qū)的公路事業(yè)具有重要意義。 本文的研究擴展了山區(qū)特殊條件下的互通式立交形式，增強了對山區(qū)環(huán)境的適應(yīng)性。
[Abstract]:Driven by the strong economic development, the domestic transportation industry is also rapidly advancing to the western mountainous areas. However, the terrain, climate, environment, traffic demand, urban distribution and so on are very different from the eastern region. Especially the interchange occupies a large area, and the contradiction with the complex conditions of mountain land is particularly prominent. At present, the mountain expressway is still directly applying the eastern design method in the construction of the interchange. The failure to combine the characteristics of highway construction in mountainous areas not only destroys the surrounding natural environment, but also brings great waste to the engineering construction. The purpose of this paper is to provide a new way of thinking for the construction of interchange under the complex environment of mountain area. On the basis of summing up the domestic and foreign literature. Firstly, the characteristics of expressway and interchange in mountainous area and the factors influencing the type selection of interchange in mountainous area are analyzed. The constraints of arranging interchange in mountain area are divided into two categories: height difference limit and plane limit. In addition to the scope of the interchanges, the paper also analyzes the interchanges and interchanges, tunnels and service facilities. The reasonable distance between toll stations. By summing up the limitation conditions of mountain interchange, the concept of variant interchange is put forward, and based on the conventional form of interchange. Based on the theoretical analysis and combined with the application of the variant interchange in practical engineering, the variant interchange is divided according to its location: the conventional form is separated from the variant interchange, and the connection line is divided into the variant interchange. On the basis of this classification, the routine ramp, the variant ramp and the connection line are combined freely, and many kinds of variant interchange forms are obtained from the driving habits. Considering the number of structural layers and the restricted conditions of mountain areas, 33 variant interchange forms were selected, and the applicability of each variant interchange form was clarified by analyzing the characteristics of each variant interchange form in detail. The design idea of interchange in the complex environment of mountainous area is developed, which is of great significance for promoting the highway undertaking in the western mountainous area. The research in this paper extends the interchanges under special conditions and enhances the adaptability to mountain environment.
