Abstract


Since the curved arch bridge , the first in the country in 1964 and , once completed , with its unique advantages , has been widely used in the construction of roads and bridges . Curved arch bridge use , there has been much concern of bridge engineering industry varying degrees of disease and injury in the Battle curved arch bridge carrying capacity . Therefore it is necessary through theoretical analysis and load test method to assess the ultimate bearing capacity of the curved arch bridge , in order to provide the basis for the technological transformation of the bridge structure . This article relying Shen the Tuen bridge carrying capacity assessment research project , summarized in the analysis of the structural features of the Double Arch Bridge , on the basis of the main factors of the disease in the form of Lesion ultimate bearing capacity analysis under the arch bridge structure theory, the use of the finite element program ANSYS the three cross- hyperbolic arch space finite element analysis model . Control sections respectively in the inter- quartile and the arch span and side spans position progressively loaded , the analysis of the ultimate bearing capacity . The papers were considered temperature change , cloth containing the way of the ultimate bearing capacity of hyperbolic arch bridge , and comparative analysis , show that the cooling of the hyperbolic - arch ultimate bearing capacity significantly affected . Paper also through entity bridge static load test , the dual nonlinear analysis of the accuracy and reliability of the finite element model of hyperbolic the connected arch bridge space in service , obtained based on the project can not meet the capacity requirements must be reinforced conclusions . The research results available for the same bridge structure reference.
