| Abstract: | Based on stability theory, the theoretical calculation of stability coefficient of high pier, cantilever casting construction and the whole bridge on the continuous rigid frame bridge with large-span and high-pier is acquired by energy methods under elastic condition. Two results obtained from the theoretical formulation of stability coefficient and software are compared, which shows that the theoretical calculation of stability coefficient reaches sufficient precision. |
