| Abstract: | The influence of interval between the two tunnels on the stability of tunnel surrounding rock has been studied. According to the calculated factors, stress fields, displacement field, plastic zone of the surrounding rock and the internal forces of the supporting frames by using the strength reduction finite element method under the different interval between double holes conditions, the interval of Songshan Tunnel was optimized and the most optimum and the smallest interval was found, and theoretical guidance for the design and construction of tunnel engineering is given. |
