【摘要】：随着大连市社会经济的发展以及人民生活水平的提高,中心城区“两城”组团式格局的发展,未来城市各组团之间将产生新的交通量。为了适应经济发展的需要,满足大连市主城区汽车保有量快速增长的交通需求,在中心城区与开发区和金州区之间修建新的通道已刻不容缓。大连湾海底隧道的建设将有效缓解大连市严峻的交通形势,解决存在的交通瓶颈问题。然而,路线设计方案选择是否合理决定了隧道建设的工程造价和规模,直接关系到对社会、经济、环境等各方面的影响和隧道建成后所产生的效益。因此,在大量交通调查的基础上,对隧道路线设计方案进行客观评价与比选显得尤为重要。本文通过查阅大量文献资料,了解国内外著名海底隧道路线方案比选过程与评价方法,并针对大连湾海底隧道的具体情况,分析大连市社会经济发展状况以及区域交通现状与发展趋势,进行实地交通调查,对数据进行整理分析。随后对影响区域进行合理划分,并采用四阶段法对划分的交通区域进行交通量的分析与预测,包括交通生成预测,交通分布预测,交通方式划分预测以及路段交通量分配预测。根据预测结果,从跨海线位、北岸登陆点和南岸登陆点三方面进行隧道路线方案的设计和比选,最终从技术层面选择沉管法线位一作为工程推荐方案。工程中对路线推荐方案运用了基于层次分析法(AHP)的模糊综合评价方法,综合各方面影响因素,分别从技术评价、经济评价、环境评价、节能评价四个方面选取16项评价指标,对推荐线位方案进行了模糊综合评价。评价结果表明,该路线设计方案可行,可以将该方案作为最终路线设计方案。
[Abstract]:With the development of Dalian's social economy and the improvement of the people's living standard, and the development of the "two cities" formation pattern in the central urban area, there will be new traffic volume among the groups in the future in order to meet the needs of economic development. It is urgent to meet the traffic demand for the rapid growth of vehicle ownership in the main urban area of Dalian, and to build a new passage between the central urban area and the development zone and Jinzhou District. The construction of the Dalian Bay Subsea Tunnel will effectively alleviate the severe traffic situation in Dalian. However, whether the choice of route design scheme is reasonable or not determines the project cost and scale of tunnel construction, which is directly related to the society and economy. Therefore, on the basis of a large number of traffic surveys, it is particularly important to evaluate and compare the tunnel route design schemes objectively. To understand the process and evaluation method of route comparison and evaluation of famous undersea tunnel at home and abroad, and to analyze the social and economic development, regional traffic status and development trend of Dalian City, and carry out field traffic investigation in the light of the concrete situation of Dalian Bay Subsea Tunnel. The data are sorted out and analyzed. Then the affected area is divided reasonably, and the traffic volume of the divided traffic area is analyzed and forecasted by using the four-stage method, including the traffic generation forecast, the traffic distribution forecast, the traffic generation forecast, the traffic distribution forecast, the traffic generation forecast and the traffic distribution prediction. According to the forecast results, the tunnel route scheme is designed and compared from three aspects: the cross sea line, the landing point on the north shore and the landing point on the south shore. Finally, from the technical level, we select the normal line of sinking pipe as the project recommendation scheme. In the project, the fuzzy comprehensive evaluation method based on AHP (Analytic hierarchy process) is used to evaluate the route recommendation scheme. 16 evaluation indexes were selected from four aspects of economic evaluation, environmental evaluation and energy conservation evaluation, and the fuzzy comprehensive evaluation of recommended line position scheme was carried out. The evaluation results show that the route design scheme is feasible. This scheme can be used as the final route design scheme.
