Study on Stability of Road and Bridge Based on Stress Analysis and Computer Modeling

Abstract

In this paper, some concepts and problems in the stress analysis design method are discussed. Based on the introduction of various types of stress characteristics, the differences between stress decomposition and stress classification are emphasized. We pointed out that the stress decomposition only relates how stress is decomposed into uniform stress, the equivalent stress distribution of linear and nonlinear stress components, how will break out of stress classification, entirely by the stress position and stress the external decision. At the same time, it also gives a valuable perspective on the distribution type of peak stress, the self-limitation and the stress decomposition and classification.
