【摘要】:城市綜合管廊建設(shè)作為城市可持續(xù)發(fā)展理念的一個重要體現(xiàn),對提升城市功能至關(guān)重要。作為未來城市發(fā)展的趨勢,在土地資源寶貴的當(dāng)代,建設(shè)綜合管廊更是首要工作和重大舉措。而如何在建設(shè)前期做好規(guī)劃工作,尤其是路徑規(guī)劃工作,使得管廊建設(shè)科學(xué)有效有序的進行,建成之后發(fā)揮其最大效益便成為亟待解決的問題。論文通過分析影響綜合管廊路徑規(guī)劃的主要因素,基于脆弱性視角提出地質(zhì)脆弱性與脆弱路段的概念,闡述二者與管廊建設(shè)之間的密切聯(lián)系。基于脆弱性視角分別建立多約束單目標(biāo)規(guī)劃模型和多約束多目標(biāo)規(guī)劃模型,并采用不同算法求解,形成多種具體的路徑方案。本文具體研究內(nèi)容如下:(1)在對地質(zhì)脆弱性概念理解基礎(chǔ)之上,根據(jù)工程地質(zhì)評價內(nèi)容建立脆弱性評價指標(biāo)體系,運用信息熵變權(quán)與區(qū)間數(shù)關(guān)聯(lián)度綜合的方法建立地質(zhì)脆弱性評價模型,為管廊建設(shè)提供地質(zhì)可建性分析。(2)依據(jù)管廊建設(shè)與路段之間的關(guān)系,提出脆弱路段概念;在影響路段脆弱性的傳統(tǒng)因素之上,考慮影響管廊管段選擇的因素,建立基于管廊建設(shè)分析的脆弱路段識別模型,對優(yōu)先建設(shè)管廊的路段給出量化判斷方法和標(biāo)準(zhǔn)。(3)以脆弱性條件為約束,在保證建設(shè)規(guī)模滿足需求的前提下,以路徑最短為目標(biāo)建立多約束單目標(biāo)規(guī)劃模型,應(yīng)用改進的人工智能蟻群算法與基本蟻群算法分別進行求解得到不同路徑方案,對比分析論證改進后算法的實用性;再以路段脆弱性最大、地質(zhì)脆弱性最小與路徑最短同時為目標(biāo)函數(shù)建立多目標(biāo)規(guī)劃模型,對蟻群算法改進的有效性與科學(xué)性進行驗證,形成多種城市地下綜合管廊路徑規(guī)劃方法;最后以某擬建設(shè)管廊區(qū)域為案例,對本文中建立的模型進行驗證,所選線路不僅符合實際的管廊規(guī)劃線路,而且與文中模型理論分析結(jié)論一致。說明本文考慮因素合理,方法實用,為形成大規(guī)模綜合管廊規(guī)劃網(wǎng)提供了具體可行的指導(dǎo)思想和方法。本文提出的脆弱性視角下城市地下綜合管廊路徑規(guī)劃模型與方法為從事綜合管廊設(shè)計的人員提供了獨特規(guī)劃視角、科學(xué)的設(shè)計依據(jù)和系統(tǒng)的操作方法,對城市綜合管廊建設(shè)前期規(guī)劃工作有重要理論指導(dǎo)意義。
[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.
