Taking the 1#'s coal trestle in the coal-smashed engine room of Shenyang thermal power plant which was set up in 1958 for example, it is discussed that when fall-off height of concrete in drawing district of reinforced concrete structural member harmed seriously in flexure increase, the bond performance of reinforcing bar and concrete deteriorate continuously and the time-dependent regulation of the weight force and deformation of structural member. Dynamic reliability indexes before and after consolidation is obtained by the method.
