【摘要】:市政道路工程建設(shè)是一項復(fù)雜的系統(tǒng)工程,其內(nèi)部各組成部分之間相互聯(lián)系又相互制約,關(guān)系錯綜復(fù)雜。其施工方案的優(yōu)劣直接影響到項目的質(zhì)量、安全、環(huán)境、進度、成本等目標(biāo)的實現(xiàn),工程項目施工方案在工程施工中占有重要地位。市政道路工程項目施工方案的優(yōu)選涉及面廣,是一個包含有定性和定量指標(biāo)的多因素和多目標(biāo)的復(fù)雜系統(tǒng)的決策問題。針對具體的市政道路工程項目的特點,建立科學(xué)的施工方案優(yōu)選決策模型,從眾多可行的施工方案中選擇適合工程項目的最優(yōu)施工方案,具有非常重要的理論研究價值和實際應(yīng)用價值。 本文的主要關(guān)鍵技術(shù)是網(wǎng)絡(luò)計劃技術(shù)、虛擬技術(shù)、模糊綜合優(yōu)化和灰色關(guān)聯(lián)分析在市政道路工程建設(shè)施工方案比選中的綜合運用。根據(jù)市政道路工程施工方案的特點,采用定性和定量相結(jié)合的指標(biāo),利用多目標(biāo)決策方法來進行施工方案優(yōu)選的決策,,建立基于工期-成本-質(zhì)量-安全-環(huán)保的灰色關(guān)聯(lián)分析的混合模糊多屬性決策模型;將施工網(wǎng)絡(luò)計劃技術(shù)、模糊綜合優(yōu)化和灰色理論應(yīng)用到市政道路工程項目的施工方案比選優(yōu)化中來,以楊家溝特大橋為例,考慮施工工期、成本、質(zhì)量、安全、環(huán)保五個施工重要指標(biāo),定義模糊集,并利用灰色關(guān)系分析進行評價,建立綜合工期-成本-質(zhì)量-安全-環(huán)保的混合模糊優(yōu)化決策模型,得出在最滿意作業(yè)模式組合下,對楊家溝特大橋的施工方案進行決策。最后應(yīng)用三維動態(tài)虛擬可視化仿真技術(shù),對楊家溝特大橋施工中的重點工序進行虛擬可視化仿真研究,可以得到合理可行的施工方案,為施工方案的優(yōu)選提供了依據(jù),實現(xiàn)了工期、質(zhì)量、成本、安全、環(huán)保等目標(biāo)的均衡優(yōu)化,有效提高了工程項目的經(jīng)濟效益和社會效益。
[Abstract]:The construction of municipal road engineering is a complex system engineering. The advantages and disadvantages of the construction scheme directly affect the quality, safety, environment, schedule, cost and other objectives of the realization of the project, the project construction scheme plays an important role in the construction of the project. The optimal selection of construction schemes for municipal road engineering projects involves a wide range of decisions, which is a complex system with qualitative and quantitative indicators. According to the characteristics of specific municipal road engineering projects, a scientific decision model for optimal selection of construction schemes is established, and the optimal construction schemes suitable for engineering projects are selected from many feasible construction schemes. It has very important theoretical research value and practical application value. The main key technologies of this paper are network planning technology, virtual technology, fuzzy comprehensive optimization and grey correlation analysis. According to the characteristics of the construction scheme of municipal road engineering, the qualitative and quantitative indexes are adopted, and the multi-objective decision-making method is used to make the decision on the optimal selection of the construction scheme. A hybrid fuzzy multi-attribute decision-making model based on time-cost, quality-safety and environment-friendly grey relational analysis is established. Fuzzy comprehensive optimization and grey theory are applied to the comparison and optimization of construction schemes of municipal road engineering projects. Taking Yangjiagou Bridge as an example, five important construction indexes, including construction duration, cost, quality, safety and environmental protection, are considered, and fuzzy sets are defined. The grey relation analysis is used to evaluate, and a hybrid fuzzy optimal decision-making model is established, which combines the construction period, cost, quality, safety and environmental protection. It is concluded that the construction scheme of Yangjiagou super bridge is decided under the most satisfactory operation mode combination. Finally, by using 3D dynamic virtual visual simulation technology, the virtual visual simulation of the key processes in the construction of Yangjiagou Bridge is carried out. The reasonable and feasible construction scheme can be obtained, which provides the basis for the optimal selection of the construction scheme. The balanced optimization of time limit, quality, cost, safety and environmental protection is realized, and the economic and social benefits of the project are improved effectively.
