摘要
借助奇异函数和叠加法，导出了带有奇异函数的三弯矩方程。其特点是选择中间支承处梁内弯矩作为多余力，利用奇异函数将弯矩方程写成一个数学表达式，并根据卡氏定理，将方程中的自由项也写成数学表达式，而不需作弯矩图，求其面积及形心位置，使计算大为简化。
The continuous beam can be soled by using singular functions and the method of superposition. The feature of the method is to select the redundants as the bedding moments in the beam at the intermediate supports. The application and selection of the method greatly simplify the calculation of the continuous beam
