【摘要】：暴雨天气的频繁发生,特别是雨季的持续强降雨天气,导致我国很多地区大面积洪涝灾害蔓延,不少城市陷入“水城”的窘境。这些年来,城市内涝问题已经越来越成为制约我国城市前进的一大障碍。每年雨季到临,总有不少城市迎来“水中看城”的景象,城市内涝问题已成为阻碍我国城市前进的一座大山。为了解决这一难题,2015年10月国务院办公厅印发了《关于推进海绵城市建设的指导意见》,积极推动海绵城市建设相关工作。《关于推进海绵城市建设的指导意见》指出,通过海绵城市建设,尽最大努力最大程度地减少城市开发建设所造成的生态环境破坏。2015年国家相关部门积极部署海绵城市建设相关任务,全国各省市也在积极响应推动海绵城市工作。伴随海绵城市任务的执行,道路施工工程正在不断推进,一系列交通问题也随之产生。海绵城市建设期间,多项道路工程同步施工必然会对原有路网结构造成不同程度的损坏,对城市交通影响范围广、持续时间长。若缺乏行之有效的施工安排,将会导致城市陷入交通拥堵甚至更为混乱的局面。本文针对海绵城市建设期间道路施工问题,研究了在保证满足所有工程期限的前提下,如何规划不同情况下的施工安排,既保证工程施工的进度,同时最大程度降低对居民正常出行的干扰。本文主要工作有:1.本文查阅相关文献,并调研了多项施工工程,总结出了若干种具有代表性的施工方式,这些施工方式同时考虑了白天和夜间两种交通流量相差较大的时段。2.根据海绵城市建设期间具体的施工情况,针对“确定性施工”及“不确定性施工”两种情况,提出多路段并发施工模型MSC2及优化算法,利用改进遗传算法对工程施工时间及施工方式进行优化,可最大限度降低居民出行成本的增加,降低了对城市出行者正常出行的干扰。3.以Sioux-Fall路网为例对模型和算法进行验证,得出了两种情况下的最优施工及排程方案,通过记录并比较不同施工方案的目标函数值,证明了算法的有效性。4.基于上述理论研究,设计并实现了多路段并发施工系统,该系统可根据具体施工城市及施工相关情况给出合理优化的施工方案,该施工方案既可满足施工的需求,同时最小化了居民出行成本。综上,本文实现了对海绵城市建设期间多路段并发施工方案研究及系统实现。系统的成功实现具有以下意义:1.为海绵城市建设期间的道路施工提供可行优化的施工方案;2.对其他情况下的道路施工起到借鉴作用;3.对施工期间居民的正常出行具有指导性意义;
[Abstract]:The frequent occurrence of heavy rain, especially the continuous and intense rainfall in the rainy season, has led to widespread flooding in many areas of our country, and many cities have fallen into the predicament of "water city." in recent years, The problem of urban waterlogging has increasingly become a major obstacle to the progress of Chinese cities. Every year when the rainy season approaches, many cities welcome the sight of "looking at the city in the water." The problem of urban waterlogging has become a big mountain hindering the progress of cities in China. In order to solve this problem, in October 2015, the General Office of the State Council issued the "guiding opinions on promoting the Construction of Sponge cities", which actively promoted the construction of sponge cities. The guidance on promoting the Construction of Sponge cities points out that. Through the construction of sponge cities, we should do our utmost to reduce the damage to the ecological environment caused by urban development and construction. In 2015, the relevant state departments actively deployed the tasks related to the construction of sponge cities, Provinces and cities throughout the country are also responding positively to the work of promoting the sponge city. With the implementation of the mission of the sponge city, road construction projects are being continuously promoted, and a series of traffic problems have arisen. During the construction of the sponge city, The synchronous construction of many road projects will inevitably cause varying degrees of damage to the existing road network structure, which will have a wide range of impacts on urban traffic, and will last for a long time. If there is a lack of effective construction arrangements, It will lead to traffic jams and even more chaos. This paper studies how to plan the construction arrangements under different conditions under the premise of satisfying all the project deadlines in view of the road construction problem during the construction of sponge city. It not only guarantees the progress of the construction of the project, but also minimizes the interference to the normal travel of the residents. The main work of this paper is: 1.This paper refers to the relevant documents, investigates several construction projects, and summarizes several representative construction methods. These construction methods take into account the different periods of traffic flow between day and night. According to the concrete construction conditions during the construction of Sponge City, the deterministic construction and the uncertain construction are considered. This paper presents a multi-section concurrent construction model MSC2 and optimization algorithm. The improved genetic algorithm is used to optimize the construction time and construction mode, which can minimize the increase of residents' travel cost. The model and algorithm are verified by Sioux-Fall road network as an example, and the optimal construction and scheduling schemes are obtained under two conditions. The objective function values of different construction schemes are recorded and compared. The validity of the algorithm is proved. 4. Based on the above theoretical research, a multi-section concurrent construction system is designed and implemented. The system can give a reasonable and optimized construction scheme according to the concrete construction city and the relevant conditions of construction. This construction scheme can not only meet the needs of construction, but also minimize the travel cost of residents. This paper has realized the research and the system realization of the multi-section concurrent construction scheme during the construction of sponge city. The successful realization of the system has the following significance: 1. Provide feasible and optimized construction scheme for the construction of the spongy city during the construction period. 2.It can be used as a reference for other road construction. 3. It is of guiding significance to the normal travel of residents during the construction period.
