摘要
研究目的:为解决目前西南复杂艰险地区隧道工程施工方案优化中没有很好兼顾环保、安全、质量导致一系列事故问题,本文综合考虑施工工期、成本、质量、安全、环保五个施工重要指标,在网络计划技术合理划分施工活动基础上,运用模糊群方法,用三角模糊数的形式表示五大指标,定义模糊多属性优属度,并利用直觉模糊集进行评价,建立综合工期-成本-质量-安全-环保的模糊优化群决策模型,并用遗传算法求得最佳作业模式组合,实现施工方案的优选决策。研究结论:(1)将模型求出的施工方案在案例隧道工程中实施,根据真实工程试验结果,在满足质量、安全、环保、工期、成本的要求基础上,工期缩短20天,成本低于预算5%,提升了工程的综合效益;(2)方法应用于隧道工程施工方案的优选决策,实现了工期、质量、成本、安全、环保等目标的均衡优化,可为隧道工程施工方案决策提供方法、数据支持和依据。
Research purposes:To address the issue that environmental protection,safety,and quality are not well taken into account in the optimization of the tunnel construction scheme in the complex and difficult area of southwest China,resulting in a series of accidents,five important construction indices,including construction period,cost,quality,safety,and environmental protection,are comprehensively considered in this paper.Based on reasonably dividing construction activities by network planning technology,the fuzzy group method is used to represent five major indexes in the form of triangular fuzzy numbers,fuzzy multi-attribute dominance degree is defined,and an intuitionistic fuzzy set is used for evaluation.A fuzzy optimal group decision model of comprehensive construction period,cost,quality,safety,and environmental protection is established,and the optimal combination of operation modes is obtained by genetic algorithm,and the optimal decision of the construction scheme is realized.Research conclusions:(1)The construction plan obtained by the model was implemented in the case tunnel project.Based on the actual engineering test results,under the requirements of quality,safety,environmental protection,construction period,and cost,the construction period was shortened by 20 days,and the cost was 5%lower than the budget,which improved the comprehensive benefits of the project.(2)The method was applied to the optimal decision-making of the construction plan for tunnel engineering,achieving a balanced optimization of the goals of construction period,quality,cost,safety,and environmental protection,providing methods,data support,and a basis for the decision-making of the construction plan of tunnel engineering.
