Abstract:
In pleatu regions, the engineering machinery has more harmful emission such as CO and HC. In order to provide scientific basis for ventilation design and pollution control of the tunnels in plateau, based on the construction of Guanjiao tunnel, the harmful gas from the loaders, excavators and dump vehicles was tested, the emission characteristics of harmful gas from engineering machinery under tunnel construction in plateau regions was studied by the way of polynomial fitting. The results show that the harmful gas such as CO and HC from engineering machinery in plateau regions varies by the way of index, it grows with the increase of rotating velocity of engineering machinery. When excess air ratio reduces, emission goes up. When excess air ratio increases, emission falls. 1 tab, 7 figs, 9 refs.
