摘　　要：首先采用传统的计算理论对某轻轨高架桥槽形简支梁的内力进行了手算.同时,还采用Midas Civil桥梁专用设计软件对槽形梁进行了电算,在对计算结果进行比较的基础上,对传统设计理论的可靠性进行了剖析和评价,并对实际的工程设计提出合理化的建议.The analysis of internal forces is the most important content and the basic precondition of bridge design. In the present paper, a calculation of the internal forces of the simple supporting trough girder in some light track viaduct has with traditional theory been made by hand at first. Owing to computers being used more and more popularly in design, the trough girder is calculated with the specially design software of Midas Civil, too. Based on the comparison of the calculated results, the reliability of the traditional design theory is analyzed and evaluated. And rational advice on practical engineering design is given.
