Soil conditioning of volcanic soil using low environmental impact agents
Abstract: EPB technology is an effective tunnelling method in urban areas when surface settlements must be avoided by controlling face stability and underground water inflow. Soil conditioning plays a major role on this aspect, although the use of additives should be limited encouraging the use of low environmental impact products. This paper analyses the conditioning process of the EPB used for the...

The two -component grouta double approach for the Young’s modulus assessment
Abstract: The two-component grout is nowadays the most widely used technology in mechanized shielded tunneling for the backfilling process. Despite its wide use, very little information is currently available on the study of its mechanical properties and their evolution as a function of the curing time. Furthermore, in several construction sites the need has recently emerged to verify the compliance of...

Use of bentonite and biodegradable slurry for cobble -rich soil conditioning
Abstract: Cobble-rich soils are always a difficult challenge for EPB-TBM tunnelling and the traditional soil conditioning through water and foam may not lead to suitable results. The addition of bentonite slurries is helpful to solve this problem but may be impaired by environmental regulations, in such cases the use of a biodegradable polymeric slurry may be a viable solution. This paper makes a...
