Abstract: Two kinds of methematical models,the dynamical model of structural reliability and the model of forecasting load,are established with the the ory of random process and structural reliability.Meanwhile,the method of any structural reliability analysis is prerented.Taking the Casing head used in Sichuan oil field for example,dynamical reliability analysis is accomplished,and the dynamical reliability curve of the Casing head which is working is solved out,the improving idea for its reliability design is presented.
