Influence of water and sand content on adhesion of clayey soils
Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutter head and conveyor system. The present study examined the effects of water and sand contents ...
Correlation of equivalent quartz content, Slake durability index and Is50 with Cerchar abrasiveness index for different types of rock
Abrasiveness is an important characteristic in excavation and tunneling projects many factors affect abrasiveness. One method for determining the abrasiveness of rocks is the Cerchar test. In this study, the effects of the ...
Assessment of the adhesion potential of kaolinite and montmorillonite using a pull-out test device
The tendency of clay particles to stick other surfaces means it is adhesive and can cause clogging of tunnel boring machines. Clogging arising from adhesion hinders or halts tunneling operations. The nature of adhesion in ...
Experimental and laboratory assessment of clogging potential based on adhesion
Mechanized tunneling through clayey formations is threatened to encounter the clogging problem. Adhesion stress as the tendency between clay and a metal surface leads to clogging between TBM and excavated materials. Some ...
