摘要
弹性地基梁内力计算的关键在于确定地基反力．目前常用的两种内力计算方法中，由于拟定的地基反力分布曲线不同，因而内力计算结果是有差别的．计算结果对比表明，链杆法计算比较精确．
The key of computing internal forces for beam on elastic foundation is to determine subgrade reaction.In the two methods in common use at present for computing internal forces,the computed values of internal forces are different as a result of the different assumed distribution graphs of foundation stress.The two methods' comparison shows that the computing results by chain rod method are more accurate
