摘　　要：本文对间距保持不变的一组移动集中荷载作用下简支梁绝对最大弯矩问题进行了深入分析,发现常规办法在通常情况下是正确的,但有些情况下当边界上某些荷载出界的最大弯矩比全部荷载同时作用是还要大。从而给出计算简支梁绝对最大弯矩的最一般方法。This paper has carried out the analysis for the absolute bending moment in the simple supported beam under the action of living concentrated load of a group of space remains unchanged, which found that conventional method was correct under normal cases, but in some cases it was wrong such as the absolute bending moment was larger when some loads out of the boundary than the moment under the integrate load. It provides a method for calculating the absolute bending load in simple beam.

关 键 词：简支梁 移动荷载 最大弯矩
