Monitoring the Variation of Rotor Pressing Forces and Horizontal Soft Soil Pressure during Shield Tunneling
Abstract: The authors carried out a geo-mechanical monitoring of shield tunneling in soft loam. The forces N in cutterhead-pressing jacks are controlled by the pressure cells in hydraulic systems at the second “Serebryanoborsky” tunnel driving (D = 14.2 m) in Moscow. The curve N oscillates. Laws of change of the horizontal component of soil pressure caused by formation of slip planes in rock mass ahead...

Recommendations for TBM-monitoring of face bentonite support
Abstract: Within the framework of the subway development strategic program more than 160 km of subway lines and 70 stations must be built during the period of 2011-2020; therefore, over 20 TBMs for the deep tunnel construction are involved [Elgaev, 2014]. Shield tunnel excavation technology contains active earth pressure balance support or face bentonite support (hydro support). Herewith it is possible...
