Abstract: The calculating method for lateral distribution of load of ribbed arch bridge is presented in this pa-per,based on the comparison of the test data with the analytic results of eccentric compressive method、continuous beam with elastic supporters and extensive G-M method.

Key words: lateral distribution of load, extensive G-M method

摘要： 本文通过肋拱桥横向分布试验，并将其横向分布试验结果与偏心压力法、弹性支承连续梁法及推力体系比拟板法的理论计算结果进行了分析对比，得出了肋拱桥横向分布计算的最佳计算方法。
