A Study On The Theory, Model And Measure Of Structural Calculating Of Energy-released Arch Bridge

After referred a great deal of data, the paper introduced the basic characteristics of the time of the existence and suitable conditions of hingeless arch bridge and ends hinged arch bridge and Energy-released arch bridge(ER arch bridge)in detail. Then based on the mechanic, the paper analysed the theory of the structural bearing(s.b.) of hingeless arch bridge and the ends hinged arch bridge thoroughly, and then summarized the theory of the s.b. of ER arch bridge, established the s.b. calculate model of ER arch bridge. Nextly, the paper introduced the classical calculate measures of hingeless arch bridge and ends hinged arch bridge that were known now, and on this foundation, andaccording to the s.b. calculate model of ER arch bridge, the paper put forworded the calculate measure of the s.b. for ER arch bridge—Addition and Integration Measure(AIM), and discussed AIM in detail.The paper also introduced the practical program that for the calculate of s.b. of ERarch bridge wrote by the author himself—SNGQ, and the usage of SNGQ wasintroduced as well at length. The carrier of SNGQ is Microsoft Excel with VBA(Office2000 or higher edition is needed, the latest edition Office was recommended) . SNGQ is capable of completing all the data calculating of s.b. for ER arch bridge automatically with least inputment by user.After the introduction of SNGQ, the author made a detail calculating of s.b. with the classical calculating measure of hingeless arch bridge for Shuanglong bridge in Dazhulin town, Chongqing on the state that it was a hingeless arch bridge before its structural system was changed from a hingeless arch bridge to a ER arch bridge use the energy-released measure(ERM), and a calculating of s.b. for it use SNGQ after the changing. At last a compare was made between the results under the tow system state and the detecting result of the real bridge, so improved that the result of SNGQ is correct.
