摘要
本文提出一种绘制支承于弹簧地基上固端梁影响线及四边固定板影响面的方法。这种方法是建立在能量原理和瑞雷（Ｒａｙｌｅｒｇｈ）－里兹（Ｒｉｔｇ）法基础上的．
This Paper gives a method of drawing the influence line of fixed end beam and the influence area of fixed edge flat plate which are lying on the elastic foundation bed.This method is based on the principle of energy and the method of Raylergh-Ritz.
