摘要
应用有限元法编制了斜板桥支反力分析程序。通过各种计算结果，研究了影响参数变化时斜板桥支反力的变化规律。在此基础上，应用多元非线性回归方法得到了斜板桥最大支反力实用设计计算公式。模型试验表明，此公式计算值比较可靠。
Finite element method is appplied to obtain an analytical program for skewedplate bridge reaction. Through many kinds of computing results, the change regulation of skewed-plate bridge reaction is studied while a numbers of influential factors are changed.On this basis, the empirical computing formula of skewed-plate bridge maximum reaction for design is obtained using poly cell nonlinear regression method. Model tests show that computing results of this formula are reliable.
