Using simulation and finite element method calculations of stress-strain state of monolithic concrete support for underground structures with non-circular outlines made of fast-hardening concrete are carried out in the paper. Based on the obtained results, the maximum stress zones and their magnitude in the reinforced concrete support are established. The stresses are compared with circular-form supports. The factors influencing the stress state of the support are determined.
