【Abstract】 The regional dynamic setting,where the wall rocks of the Qinling tunnel in the railway of xi’an to Ankang occurs,and the nature of the present stress field of the wall rocks are analyzed in this contribution.According to the feature of the rockburst in the tunnel,the relationship between the rockburst and the regional dynamic setting is discussed in terms of evolution of Qinling orogen.At last,some measures are proposed to avoid or alleviate the harm of rockburst in long and deep buried tunnel in the Mesozoic and Cenozoic orogens.更多还原
