... excavation machines that commonly used in mine and tunnel projects for excavation of shafts. This study aimed to analyze the effect of intact rock properties (uniaxial compressive strength and indirect tensile strength) and RQD (rock quality designation), as well as fault zones on the performance of a RBM...

... is developing a numerical method for a benchmark model to simulate the injection test in a single fault zone. We present a numerical model to reproduce the coupled hydro-mechanical process of fault activation using the TOUGH-FLAC simulator. The mechanical behavior of a single fault is represented by the zero...

... Abstract The Yansan fault is the biggest fault zone in Korea Penninsula the length of which about 120km and the displacement 25km. The high speed railway tunnel of 3,320m in length was constructed to go through this fault zone. For the safety design of the tunnel, it was required...

... and C. Two of the geophone boreholes, A and B were located in the chain pillars to either side of LW3-S and straddled the fault zone. Borehole C was located at the finish line for the panel. The geophones in each of the boreholes were arranged from the floor of the GM seam to 200 m above the seam...

... with the design challenges of the multifunction station Faido which consists of an extremely complicated combination of main tunnels, galleries and caverns in a very difficult geology with several fault zones. Some caverns and the crossovers cut the main tunnels in an acute angle. At some intersection points...

... ABSTRACT It has been widely reported that fault zones are the most influencing factor of tunnel collapse. This study reviewed the applicability of the 3-D absolute displacement measurement of a tunnel by using digital vision monitoring. Also analyzed is the behavior of a tunnel displacement...

... rock formations and one fault zone at Scllafield, UK. The results show that the mechanical REV is around 10 m x 10 In for all the formations considered and the R.EV and equivalent properties arc subject to the block size and fracture properties. The results demonstrate that the OEM madding can...
