| Abstract: | According to the basic principle of finite element method, some numerical tests and analyses are used for the stress condition of Niuhushan tunnel, which is six-lane superhighway of double lines, constructed in Huizhou in Guangdong Province. And the results were compared with those from the general tunnel and simplified formulas of norm. Some distribution rules of large-span tunnel surrounding rock stress are included, in order to provide the reasonable foundation for similar engineering construction in future. |
