【摘要】：随着我国城市化进程的逐步加快,城市土地利用变更会带来一系列交通问题,而交通影响分析恰恰是作为协调项目建设与交通关系的一种特别有力的工具,对城市建设项目进行交通影响分析已然是势在必行的。然而交通影响范围的确定是交通影响分析中一个比较热点和难点问题,因此如何确定出一种适合我国国情和道路交通特点的交通影响范围量化方法是当下的重点问题。本文对交通影响分析理论和方法进行了阐述,详细分析了国内外确定交通影响范围的模型和方法,并确定本研究的突破方向。对爆炸冲击波基本理论进行研究,探讨了描述爆炸破坏效应的冲击波峰值超压公式,并归纳出通用的冲击波峰值超压解析式。对交通影响范围的影响因素进行分析,概括出主要应考虑的影响因素。在上述理论研究的基础上,提出交通影响范围模型建立的基本思想和交通影响范围模型建立的假设;在对爆炸冲击波峰值超压公式进行求解的基础上,以拟建商业购物中心、拟建工业物流中心、拟建住宅小区这三类用地性质的新建项目为例,对他们的交通特性进行分析,并分别建立了基于爆炸冲击波理论的交通影响范围模型,提出了交通影响范围确定的流程图。利用TransCAD进行交通影响范围的研究,提出了基于TransCAD的交通影响范围预测流程。最后结合淄博市某建设项目,运用本文提出的理论和方法确定该建设项目的交通影响范围并进行交通影响分析,从而验证了本文所提理论方法的可行性和实用性。
[Abstract]:With the gradual acceleration of urbanization in China, urban land use change will bring a series of traffic problems, and traffic impact analysis is a particularly powerful tool to coordinate the relationship between project construction and traffic. It is imperative to analyze the traffic impact of urban construction projects. However, the determination of traffic impact range is a hot and difficult problem in traffic impact analysis. Therefore, how to determine a quantitative method of traffic impact range which is suitable for our country's national conditions and road traffic characteristics is a key issue at present. In this paper, the theory and method of traffic impact analysis are expounded, the models and methods to determine the range of traffic impact at home and abroad are analyzed in detail, and the breakthrough direction of this study is determined. In this paper, the basic theory of blast wave is studied, the formula of peak overpressure of shock wave describing the effect of explosion failure is discussed, and the general analytical formula of peak overpressure of shock wave is concluded. The influence factors of traffic influence range are analyzed, and the main factors should be considered are summarized. On the basis of the above theoretical research, the basic idea of establishing the traffic impact range model and the hypothesis of the traffic impact range model are put forward. On the basis of solving the formula of peak overpressure of explosion shock wave, taking the three kinds of new projects of commercial shopping center, industrial logistics center and residential district as examples, the traffic characteristics of these three kinds of new projects are analyzed. The traffic impact range model based on blast shock wave theory is established, and the flow chart of traffic impact range determination is presented. In this paper, TransCAD is used to study the traffic impact range, and the prediction flow of traffic impact range based on TransCAD is put forward. Finally, combined with a certain construction project in Zibo City, the theory and method proposed in this paper are used to determine the scope of traffic impact of the construction project and traffic impact analysis is carried out, which verifies the feasibility and practicability of the theory and method proposed in this paper.
