... Abstract Many accidents may occur during tunnel construction because the strata ahead of the working face are not clear; therefore the advanced percussive drilling surveying method is proposed which is one direct convenient, fast and inexpensive geological forecast method. The prediction...

... source that was used on the tunnelwall and floor. Fractures were imaged couple of hundred meters away from the tunnel. The location of the target features was achieved by using 3-component receivers, two parallel source lines and 3D vector migration schemes. IP (Image Point) migration was found...

... underground caverns is a typical 3D spatial process, which is obviously different from that used for opening of general tunnels. The features of 3D spatial excavation bring about a problem for designers in two aspects at least. First, the interaction between caverns and tunnels leads to the complicated...

... Abstract In a shallow-buried and soft surrounding rock road tunnel, landslides in working face frequently occurred. It is necessary to timely explore the geology in front of the working face such as litho-logy, moisture content and so on. Ground Penetrating Radar can forecast the moisture...

... failure plane is formed. In order to study the strength properties of such microfissure rocks, and provide basic data for investigating the water inflow and mud burst mechanism of tunnel excavated in microfissure-well-developed rocks, a series of triaxial compression tests under different loading path...

... engineering risk conditions, we describe the predictable and unpredictable nature of different projects and highlight ‘black swan’ events. This is followed by an explanation of epistemic and aleatory uncertainty, and how these are both reduced as rock excavation proceeds. An illustrative example of a tunnel...

... 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...

... Abstract Muzhailing railway tunnel is excavated mainly in fault zones, carbonaceous slate and sandstone using the drilling-blasting method. Geotechnical problems encountered in the tunnel during construction, such as large squeezing deformation with long duration and collapse of arch crown...

... Abstract Parallel tunnels with super-small-interval means that the interval of two parallel tunnels is between 1/2–1/3 tunnel span. Its stress condition of surround rock is more disadvantageous compare with the tunnels normal and small-interval tunnel during the tunnels with super-small...

...: For an analysis of the stability of an underground excavation in two dimensional space, the convergence confinement tunnel design process is usually applied to investigate the interaction of support and ground of the excavation. In order to achieve the design process, a coefficient of stress release is defined...

... Abstract The inherent uncertainties in the ground model and influencing factors, in most cases, do not allow a reliable direct design of a tunnel. Empirical tunnel design methods do not allow proofing stability or serviceability, thus are not acceptable according to common understanding...
