摘　　要：在建筑工程领域里,结构多承受线荷载、面荷载和体荷载作用。针对简支梁在均布荷载作用下的平衡状态,建立结构的力学模型,考虑结构受力、位移和构造等约束条件,结合微分方程的求解原理,建立目标函数,求解结构未知荷载,并把结果与有限元分析结果进行比较,进而验证优化算法的正确性。In the field of construction engineering,the structure is subjected to line load,surface load and body load.In paper,the simply supported beam build mathematical model under uniform load,with consideration of conditions such as structure,displacement and structure.The objective function is established to solve the unknown load of the structure based on the principle of solving differential equation.The results are compared with the results of finite element analysis to verify the correctness of the algorithm.
