Recent experience in solution of geotechnical problems during subway tunneling in Moscow

Abstract

Moscow subway is one of the world’s leaders in transportation. Moscow subway extension is a vital and urgent task for the authorities and engineers. Subway tunnelling requires using new design solutions, techniques and careful planning. However, widespread application of progressive construction methods does not always allow to achieve reliable efficiency in underground subway construction, mostly because of geotechnical risks impact. Mitigation of geotechnical risk becomes an actual task during subway tunnelling, providing security and saving costs and time. The most effective action to avoid geotechnical risk is scientific maintenance, which allows using the previous experience and making careful analysis, to choose the proper construction methods or develop an effective strategy during accidents.
