Analysis And Evaluation Of Potential Carrying Capacity Of Stone Arch Bridge

Stone Arch Bridge is the most ancient and most important, one of the most sophisticated bridge. Although the transport development and scientific and technological progress, all kinds of bridge emerging, but the stone arch bridge is still on to play an important role. Early modern period of increased traffic on the construction of the stone arch bridge made higher demands. Therefore, the use of correct assessment methods to evaluate the carrying capacity of active stone arch bridge has been widely appreciated.This paper describes the development history of China stone arch bridge stone arch bridge at home and abroad on the status of ultimate bearing capacity. Changning Bridge as a background to, based on ultimate bearing capacity of stone arch bridge the basic theory, there is a stone arch bridge carrying capacity of the three factors of safety reserves. Space model using the finite element and, on the impact of stone arch bridge carrying capacity limit of the factors analyzed in depth; and real bridge Static Load Test by combining finite element analysis, obtained in considering the construction and stone arch bridge arch on the bridge deck O'clock Arch carrying capacity is greater than the carrying capacity of bare conclusions, and recommend a stone arch bridge with the potential carrying capacity of the Theory.This study will help understand the Stone Arch Bridge Stone Arch Bridge structure and impact of the factors used for many years in active service after stone arch bridge carrying capacity assessment of the limits, safety evaluation with constructive suggestions.
