Abstract:
HefeiWuhan passengerdedicated railway goes through the nonmetamorphic zones of Dabieshan mountainous area. During the construction of the tunnels on the railway, fire accidents occur. Insitu measurements and chemical tests are made to determine the compositions of the rocks and gases and the geotectonic theory is used to probe into the gas gushing mechanisms, on basis of which technical construction countermeasures are recommended. Therefore, the construction of the tunnels are under safe and reliable control during the complete construction course. The technology has been preliminarily used in the construction of the tunnels on HefeiWuhan passengerdedicated railway and good effects have been achieved.
Key words: passengerdedicated railway  , tunnel gas  , gas gushing mechanisms  , construction countermeasure
