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...

Mechanical improving of granular soils by permeation grouting: results of laboratory tests
Abstract: The injection of natural soil using proper mixes is one of the most effective ground improvement technique. Consolidation and waterproofing are the two main purposes of these treatments, both in granular soils and in rock masses. The application field of these materials, depends on many external parameters, related to the characteristics of the soil, the injection mixes and injection techniques...

Wear in Granular Soils: results of a new procedure by using a soil abrasion testing apparatus with a wear disk
Abstract: The wear phenomenon in mechanized excavation machines is very complex. Many parameters play key roles in wear and in EPB machines wear in all areas where there is a continuous friction between ground and steel. Because of the complex nature of phenomenon, to design a laboratory test procedure and a laboratory test device that can provide correct results in terms of predicting of wear is not...
