为了准确评估隧道施工过程中环境质量对人的影响,在分析隧道施工环境质量影响因素的基础上,选取粉尘质量浓度、CO质量浓度、环境噪声、环境震动、热环境和光环境6项指标,建立了隧道施工环境质量评价指标体系,运用博弈论将主观赋权法(层次分析法)和客观赋权法(简单关联函数法)相融合,结合可拓学理论,构建了隧道施工环境可拓评估模型。结合浙江省奉化市石郎山隧道段右线yk1+430~yk2+280区间内4道不同施工工序实测数据,应用该模型评价了隧道施工环境。结果表明,构建的模型能够综合反映各指标信息,将独立的单指标环境质量分析上升为系统化的综合环境评估,模型能更客观地反映施工环境状况。
In order to accurately assess the impact of environmental quality on people during the tunnel construction, based on the analysis of influencing factors on tunnel construction environmental quality, six indexes of dust mass concentration, CO mass concentration, environmental noise, environmental vibration, thermal environment and light environment were selected to establish The evaluation index system of tunnel construction environment quality is proposed. By using the game theory, subjective weighting method (AHP) and objective weighting method (simple correlation function method) are integrated. Based on the theory of extenics, an extension assessment of tunnel construction environment model. Combined with the measured data of 4 different construction processes in yk1 + 430 ~ yk2 + 280 on the right line of Shilangshan tunnel section in Fenghua City, Zhejiang Province, this model was used to evaluate the tunnel construction environment. The results show that the model can comprehensively reflect the information of each index, and raise the independent single-index environmental quality analysis to a systematic comprehensive environmental assessment. The model can more objectively reflect the construction environment.
