摘　　要：为了提高钢筋混凝土圆管涵的设计水平,承包商需要深入研究中美规范。研究结果表明,中美规范都采用三点试验法评价钢筋混凝土圆管涵的抗压强度,但在分类方法、材料要求、抗渗性能、合格标准等方面存在较大差异;适当增加水泥用量,钢筋混凝土圆管涵的抗压强度会有所提高。In order to enhance the design level of reinforced concrete circular culvert,the contractor needs to study Chinese and American specifications in depth.The results of this paper show that both Chinese and American specifications take three-edge-bearing test to evaluate the compressive strength of reinforced concrete circular culvert,while there are many differences in following aspects,method of classification,requirement of material,performance of seepage prevention and criterion of acceptability.The compressive strength of reinforced concrete circular culvert can be improved when the dosage of cement is increased appropriately.
