Numeric simulation of xiefeng mountain tunnel ventilation 雪峰山隧道通风数值模拟研究
However , a beautiful town named dongkou lies in the east hillfoot of it , where is just like a mother ' s spreading bosom 然而,就在这雪峰山的东麓,在雪峰山母亲般伸展屈曲的怀抱里,躺着一座秀美如画的小城?洞口。
The result is that the probability of high tensity rockburst in the tunnel is non - existent and the probability of lowgrade and moderate tensity rockburst in the tunnel is existent 预测结果表明,雪峰山隧道不会出现高烈度的岩爆,但某些地段可以出现级或级的岩爆。
The third steppe , about 500 - 1 , 000 meters in elevation , begins at the line from the greater hinggan , taihang , wushan and xuefeng mountain ranges eastward to the seacoast 第三个台阶则是由大兴安岭、太行山、巫山和雪峰山向东一直到达海岸,地势下降到海拔500米到1000米以下。
These study results can offer scientific grounds for choosing the optimum construction method in the construction of xuefengshan tunnel and other engineering of the same kind under the different conditions of surrounding rock 这些研究成果可为雪峰山隧道及其它同类工程在不同的围岩地质条件中,选择最佳的施工方案提供科学的参考依据。
