... Abstract In order to address on the high-geothermal issue of the power tunnel of Bulunkou-Kongur hydropower station, an analytical method was first used to evaluate the temperature distribution and mechanical characteristics of surrounding rock and lining structures of high temperature tunnel...

... lines in mountainous area, which will reduce the width of highway and the amount of stonework of blasting. For the parallel tunnel in I–IV class surrounding rock, the design of super-smallinterval tunnels is not only a method have to be aim at any special condition, but also a regular choice of tunnel...
