Assessment of Stress State in a Heterogeneous Cross-section from Steel and Shotcrete at Primary Tunnel Lining

Popis výsledku v původním jazyce

A heterogeneous cross-section of a primary lining structure made of shotcrete and steel elements is a standard design in tunnel construction. The cross section is put together of shotcrete installed minimally in two strata and steel lattice arches reinforcement embodied in shotcrete. The shotcrete combines all steel elements into one structure unit and it embedded to the ground around an excavation. This design provides consistency between lining structure and ground. The article displays two approachesan analytical and a numerical to evaluate the stress state in a materially heterogeneous cross-section. The analytical approach figures out the stress in the concentric multi ring formation via functions of the complex variable. The numerical approach employs 3D model to perform the same task. The both approaches take into account all essentials to exemplify a structure of the heterogeneous cross-section of a tunnel lining. They satisfy crosssection construction phases, hardening of sho
