【摘要】：分離式立交使路網(wǎng)節(jié)點(diǎn)處交通流在空間上分離,消除了交通沖突,保證了直行車流安全、快速運(yùn)行。隨著路網(wǎng)的密集度增加,分離式立交的作用越來(lái)越明顯,而關(guān)于分離式立交的設(shè)置條件、技術(shù)指標(biāo)的選取還存在諸多問題亟待解決。本文以國(guó)內(nèi)外研究理論為依據(jù),通過理論研究、統(tǒng)計(jì)分析并與實(shí)際問題相結(jié)合的方法,對(duì)分離式立交設(shè)置條件及關(guān)鍵技術(shù)指標(biāo)選取進(jìn)行研究,研究?jī)?nèi)容包括道路功能對(duì)交叉形式選擇的影響、分離式立交設(shè)置的交通量條件、分離式立交合理間距確定、分離式立交合理凈空選擇、分離式立交合理交角范圍。根據(jù)路網(wǎng)規(guī)劃、道路功能對(duì)道路等級(jí)、控制標(biāo)準(zhǔn)的要求,建立道路功能、等級(jí)與交叉形式關(guān)系,初步確定交叉處可選用的交叉形式范圍�；诳山邮荛g隙理論、車隊(duì)理論分別研究主路優(yōu)先、自由行駛無(wú)信號(hào)平面交叉通行能力計(jì)算方法,結(jié)合國(guó)內(nèi)對(duì)無(wú)信號(hào)平面交叉交通特性參數(shù)調(diào)查,以無(wú)轉(zhuǎn)彎需求為前提,計(jì)算無(wú)信號(hào)平面交叉通行能力,提出次干線一級(jí)公路、二級(jí)公路設(shè)置分離式立交交通量條件。采用飽和流率法,借鑒日本立體交叉交通量規(guī)劃方法,提出二級(jí)、三級(jí)、四級(jí)公路間交叉設(shè)置分離式立交的交通量條件。分析影響分離式立交間距的因素,引入節(jié)點(diǎn)重要度概念,結(jié)合聚類分析法,建立了分離式立交合理間距計(jì)算模型,對(duì)比美、日標(biāo)準(zhǔn)分析分離式立交凈空要求,結(jié)合實(shí)際問題,提出了確定分離式立交合理凈空的方法。從滿足經(jīng)濟(jì)、利于施工標(biāo)準(zhǔn)化、受力安全角度出發(fā),確定了分離式立交交角合理范圍。
[Abstract]:The separated interchange separates the traffic flow at the node of the road network in space, eliminates the traffic conflict, and ensures the safety and fast running of the direct traffic flow. With the increase of the density of the road network, the function of the separated interchange becomes more and more obvious. However, there are still many problems to be solved in the selection of technical indexes about the setting conditions of separation interchange. This paper is based on the domestic and foreign research theories, through theoretical research, statistical analysis and the method of combining with practical problems. This paper studies the setting conditions and key technical indexes of separated interchange, including the influence of road function on the choice of cross form, the traffic flow condition of separation interchange, and the determination of reasonable distance between separated interchange, According to the requirements of road network planning, road function to road grade and control standard, to establish the relationship between road function, grade and cross form, according to the reasonable clearance selection of separated interchange, the reasonable angle range of separation interchange, and the requirements of road network planning, road function and control standard, Based on the acceptable gap theory, the motorcade theory respectively studies the calculation method of the crossing capacity of the main road with no signal and no signal. Based on the investigation of traffic characteristic parameters of unsignalized plane crossing in China, and on the premise of no turning requirement, the traffic capacity of unsignalized plane crossing is calculated, and the sub-trunk first class highway is put forward. The second class highway sets up the separation type interchange traffic volume condition, uses the saturated flow rate method, draws lessons from the Japanese three-dimensional cross traffic volume planning method, proposes two, three levels, This paper analyzes the factors that influence the separation interchange spacing, introduces the concept of node importance, and establishes a reasonable distance calculation model of separated interchange with cluster analysis method. According to the daily standard analysis of separation interchange clearance requirements, combined with practical problems, this paper puts forward a method to determine the reasonable clearance of separation interchange. From the point of view of satisfying the economy, facilitating the construction standardization and force safety, The reasonable range of the angle of separation interchange is determined.
