摘　　要：交通基础设施建设快速发展,环境污染问题得到人们普遍重视。为此以评价地震断裂带隧道施工扬尘造成的环境污染为目的,选取大气环境、气候环境、水资源环境以及自然生态环境评价指标,构建地震断裂隧道施工扬尘对环境污染评价模型;建立环境污染分布函数,选取概率等级作为环境污染评价等级划分标准,计算各环境污染评价指标的污染等级。实验结果表明所构建模型能够获取准确的地震断裂带隧道施工扬尘环境污染结果,可有效改善各评价指标环境污染情况。With the rapid development of transportation infrastructure construction,environmental pollution has been paid more and more attention.Therefore,in order to evaluate the environmental pollution caused by dust in the construction of tunnel in earthquake fault zone,the evaluation indexes of atmospheric environment,climate environment,water resources environment and natural ecological environment are selected to construct the evaluation model of environmental pollution caused by dust in the construction of earthquake fault tunnel;the distribution function of environmental pollution is established,and the probability grade is selected as the classification standard of environmental pollution evaluation level,and the environment is calculated The pollution grade of pollution evaluation index.The experimental results show that the model can obtain accurate results of dust pollution in tunnel construction in seismic fault zone,and can effectively improve the environmental pollution of each evaluation index.
