考虑碳排放和交通拥堵的坝料绿色运输仿真与优化模型研究OA
Simulation and optimization of green transportation of dam materials considering carbon emission and traffic congestion
堆石坝施工涉及大规模坝料运输,燃油自卸汽车运输会排放大量二氧化碳,且车队密集运输引起的排队拥堵现象是影响施工进度的重要因素.然而现有堆石坝交通仿真模型无法根据机械特性量化碳排放量,且缺乏考虑道路规模(弯度、坡度、宽度等)对交通拥堵的影响,难以为绿色施工管理提供有效的决策优化建议.针对上述问题,耦合CYCLONE排队模型与微观交通运动模型,建立了考虑碳排放和交通拥堵的坝料绿色运输仿真模型,量化不同道路布设和机械配置情况下的运输进度、成本、道路饱和度和排放指标;进而结合多利益相关方协同的多属性决策方法,提出综合考虑政府、施工、居民多方利益需求的运输方案决策方法,化解了方案选择过程中各利益方的观点冲突,为绿色发展目标下堆石坝施工方案优化提供决策指导.案例分析表明,相比于现有仿真模型,本研究提出的方法可量化碳排放量与交通拥堵指标,平均月运输强度、最大月运输强度和工期与实际值的相对误差分别减少15.1％、9.5％和12.7％.通过多利益相关方协同的多属性决策方法得到了各施工方案排序,可为绿色施工管理提供有效的决策优化建议.
The construction of rockfill dams involves large-scale transportation of dam materials.The transportation of fuel-powered dump trucks emits a large amount of carbon dioxide,and the queuing congestion caused by the dense fleet of trucks is an important factor affecting the construction progress.However,the current traffic simulation model for rockfill dams cannot quantify carbon emission based on mechanical characteristics,and it lacks consideration of the impact of road scale(curvature,slope,width,etc.)on the traffic congestion,making it difficult to provide effec-tive decision-making optimization suggestions for green construction management.To address the above issues,the CYCLONE queuing model and the micro-traffic motion model are coupled to establish a simulation model for green transportation of dam materials considering carbon emission and traffic congestion,quantifying the transportation progress,cost,road saturation,and emission indexes under different road layouts and machinery configurations.Fur-thermore,the multi-attribute decision-making method with the collaboration of multiple stakeholders is proposed to comprehensively consider the interests of the government,construction,and residents.This resolves the conflicts of views among various stakeholders during the scheme selection process,and provides decision-making guidance for optimizing the construction scheme of the rockfill dam under the goal of green development.Case analysis shows that compared with the current simulation models,the method proposed in this study can quantify carbon emission and traffic congestion indexes.The relative errors of the average monthly transportation intensity,the maximum monthly transportation intensity,and the construction period with respect to the actual values are reduced by 15.1％,9.5％,and 12.7％,respectively.The ranking of each construction plan is obtained through the multi-attribute decision-making method with multi-stakeholder collaboration,providing effective decision-making optimization suggestions for green construction management.
