摘　　要：以某长大隧道为工程背景,利用Mobile模型和Gauss模型对隧道竖井污染物的排放进行计算,得到了主要污染物在近地二维平面上的一次扩散浓度。引入稀释空气因子的概念综合评价了污染物的环境影响。通过正交试验设计和显著性分析的方法确定了几个主要影响因素的显著性水平,指出从源头上降低污染物的排放是在治理过程中应着重加强的环节。It is calculated the waste gas discharge from a long tunnel shaft with the Mobile model and Gauss model theory,the primary diffusion concentration on the plane near the floor is got.A dilute-air factor is defined to evaluate the environmental effect,and then the notabilities of four main affecting factors are analyzed with the orthogonal test and notability analysis method,showing that a great emphasis should be laid on the control of the waste gas source to abate the environmental effect by the tunnel shaft.
