Analysis of Rock Mass Based on Rock Characterization by Roofbolt Drilling and 3D Data Visualization in Tunneling
Abstract: 3D visualization of the rock strata and ground conditions for determining the rock mass properties in underground construction, tunneling, and mining is a powerful tool that can help in optimization of ground support design. The required input data can be generated by combining the information obtained through original geotechnical exploration boring and drilling the boreholes such as...

Development of a soil abrasion test and analysis of impact of soil conditioning on tool wear for soft ground...
Abstract: In the recent years, Earth Pressure Balance (EPB) shields have been successfully used in many tunnels in urban areas. One of the critical issues for successful EPB tunneling is the use of proper soil conditioning to reduce wear and torque. Among the parameters that can affect tool wear, soil conditioning is the most important one that can be controlled by the operators. Soil conditioning has...

Experimental investigation on effect of ambient pressure of conditioned soil on tool wear in earth pressure balance...
Abstract: The use of mechanized excavation especially shielded tunnel boring machines (TBMs), has grown rapidly in various soft ground tunneling projects. One of the advantages of mechanized tunneling compared to conventional method is the ability of the machines in coping with various geological conditions. In the recent years, Earth Pressure Balance (EPB) shields have been successfully used in many...
