... 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...

Wang National Taipei University of Technology, Taipei Tsan-Hwei Huang National Taiwan University, Taipei ABSTRACT: This manuscript established an innovative approach for recognizing deformation patterns of a built tunnel, which benefits for diagnosing possible causes for lining anomalies. Demonstrating...

... are listed. Prevention of hydrojacking, management of seepage and knowledge of the specific characteristics of the rock masses where the tunnel is to be excavated will dictate the layout, as well as support/lining or treatment to be applied for the different sections of the works. Emphasis is put on proper...

The rock mass is assumed brittle and the horizontal to vertical stress ratio is varied. Selected tunnel responses of the openings for the original HB...
