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...

Optimization of geological researches for subway planning in Moscow
Abstract: The engineering-geological information for designing and building the metro tunnels is characterized by considerable randomness due to the discreteness of its procuration. This is confirmed by revelations of many native [Pashkin, 2013] and foreign [Charles, 1976] specialists. Even the detailed researches received according to the normative documents existing in the country then lead to the...

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...

Solutions for minimization the soil settlement using EPBM innovations
Abstract: As is known, the maximum reduction in the earth's surface displacement may be achieved if Slurry Shield applies. In this paper we propose measures to improve the work of the EPB-Shield based on new structural and design solutions. Recommendations were developed for planning replacements of the cutting wheel. When scheduling a replacement of the cutting wheel rock abrasiveness indicator should...
