摘要
对具有一边简支支承的部分悬空、部分支承在温克勒弹性地基上的板作为整体式桥头搭板的力学计算模型，采用样条子域法建立了桥头搭板内力计算的基本公式，并编制了计算程序。将计算结果与桥头搭板室内模型试验的结果进行了对比，证明所建立的力学计算模型是正确的，计算程序可以应用于工程设计中。
The mechanical model of approach slabs is assumed as a slab partially supported on the winkler foundation,with the unsupporting blocks and the simple support on the one of its sides.The spline subdomain method is adopted in the program computing the internal forces in the slabs,and the essential formulas are given.By comparing with test data from the laboratory model test,it is correct,and able to use in practical engineering.
