The sectional stresses (M, N) in a gallery lining are computed comparatively numerical by FEM taking into account the interaction underground structure – surrounding ground and analytical by Protodiakonov method. The last method is based on coincidence arch born in ground over gallery. Comprehensive analyses allow to settle the domain in which Protodiakonov method can be applied as well as the ...

The lack of accurate maps of subsurface utilities and other underground hazards often causes accidents, project delays and increased project cost. Subsurface Utility Engineering (SUE) is an engineering process utilizing state-of-the-art technology to accurately identify, characterize, and map underground utilities and installations prior to the design of new highways and structures or the insta...
