【摘要】：城市综合管廊建设作为城市可持续发展理念的一个重要体现,对提升城市功能至关重要。作为未来城市发展的趋势,在土地资源宝贵的当代,建设综合管廊更是首要工作和重大举措。而如何在建设前期做好规划工作,尤其是路径规划工作,使得管廊建设科学有效有序的进行,建成之后发挥其最大效益便成为亟待解决的问题。论文通过分析影响综合管廊路径规划的主要因素,基于脆弱性视角提出地质脆弱性与脆弱路段的概念,阐述二者与管廊建设之间的密切联系。基于脆弱性视角分别建立多约束单目标规划模型和多约束多目标规划模型,并采用不同算法求解,形成多种具体的路径方案。本文具体研究内容如下:(1)在对地质脆弱性概念理解基础之上,根据工程地质评价内容建立脆弱性评价指标体系,运用信息熵变权与区间数关联度综合的方法建立地质脆弱性评价模型,为管廊建设提供地质可建性分析。(2)依据管廊建设与路段之间的关系,提出脆弱路段概念;在影响路段脆弱性的传统因素之上,考虑影响管廊管段选择的因素,建立基于管廊建设分析的脆弱路段识别模型,对优先建设管廊的路段给出量化判断方法和标准。(3)以脆弱性条件为约束,在保证建设规模满足需求的前提下,以路径最短为目标建立多约束单目标规划模型,应用改进的人工智能蚁群算法与基本蚁群算法分别进行求解得到不同路径方案,对比分析论证改进后算法的实用性;再以路段脆弱性最大、地质脆弱性最小与路径最短同时为目标函数建立多目标规划模型,对蚁群算法改进的有效性与科学性进行验证,形成多种城市地下综合管廊路径规划方法;最后以某拟建设管廊区域为案例,对本文中建立的模型进行验证,所选线路不仅符合实际的管廊规划线路,而且与文中模型理论分析结论一致。说明本文考虑因素合理,方法实用,为形成大规模综合管廊规划网提供了具体可行的指导思想和方法。本文提出的脆弱性视角下城市地下综合管廊路径规划模型与方法为从事综合管廊设计的人员提供了独特规划视角、科学的设计依据和系统的操作方法,对城市综合管廊建设前期规划工作有重要理论指导意义。
[Abstract]:As an important embodiment of the concept of urban sustainable development, the construction of urban comprehensive management gallery is very important to promote the function of city. As the trend of urban development in the future, the construction of integrated management gallery is the most important work and major measure in the present age when land resources are precious. However, how to do the planning work well in the early stage of construction, especially the path planning work, makes the construction of pipe gallery scientific, effective and orderly, and it becomes an urgent problem to be solved to give full play to its maximum benefit after completion. Based on the analysis of the main factors affecting the path planning of the integrated pipeline corridor, the concept of geological vulnerability and vulnerable section is put forward based on the vulnerability perspective, and the close relationship between the two and the construction of the pipeline corridor is expounded. Based on vulnerability perspective, the multi-constrained single-objective programming model and multi-constrained multi-objective programming model are established, and different algorithms are used to solve them to form a variety of specific path schemes. The specific contents of this paper are as follows: (1) on the basis of understanding the concept of geological vulnerability, a vulnerability evaluation index system is established according to the content of engineering geological evaluation. The evaluation model of geological vulnerability is established by using the method of information entropy variable weight and interval number correlation degree, which provides geological buildability analysis for the construction of pipe corridor. (2) according to the relationship between the construction of pipe corridor and the section of road, the concept of vulnerable section is put forward. On the basis of the traditional factors that affect the vulnerability of the section, considering the factors that affect the selection of the pipe section, the identification model of the vulnerable section is established based on the analysis of the construction of the pipe corridor. The quantitative judgment method and criterion are given for the section of priority construction pipe corridor. (3) taking the vulnerability condition as the constraint and ensuring the construction scale to meet the demand, the multi-constrained single-objective programming model is established with the shortest path as the goal. The improved artificial intelligence ant colony algorithm and the basic ant colony algorithm are used to solve the different path schemes, and the practicability of the improved algorithm is analyzed. The minimum geological vulnerability and the shortest path simultaneously establish a multi-objective programming model for the objective function, verify the effectiveness and scientific nature of the ant colony algorithm improvement, and form a variety of urban comprehensive pipeline path planning methods. Finally, a case study of a pipeline corridor area is given to verify the model established in this paper. The selected lines are not only in line with the actual pipeline corridor planning line, but also consistent with the theoretical analysis results of the model in this paper. This paper shows that the factors are reasonable and the method is practical, which provides a concrete and feasible guiding ideology and method for the formation of a large-scale integrated pipe corridor planning network. The model and method proposed in this paper provide a unique planning perspective, scientific design basis and systematic operation method for the personnel engaged in the integrated pipe corridor design. It is of great theoretical significance to the early planning of urban comprehensive pipe gallery construction.
