| Abstract: | Aiming at section - intension and stability of naked arch in process of construction, combined with design and construction norms, section stability and bearing capacity are checked, and finite element analysis is carried out as well. The influence of having rein - force arch or not and de - moulding sequence on section intension and stability are analyzed , and on the basis of calculation reasonable construction controlling is put wards. |

| Keywords: | semi - circle arch construction section intension stability |
