| 摘 要： | 以战时桥梁设施的毁伤及抢修为背景，针对钢筋混凝土桥梁的主梁在战时遭受精确打击后造成毁伤的问题，对其桥跨结构进行了适当的简化，并在此基础上分析和归纳了3类主梁、18种不同的毁伤模式和效果。提出了受损主梁最不利截面的确定方法，给出了主梁毁伤后剩余承载力的计算方法。

| Abstract: | Considering the destruction and repair for bridges used in wars, a research method for destruction effect on span structure in RC bridges used in wars, hit by precision weapons, is presented. Span structure is appropriately simplified. Three types of main girder of span structure are analyzed and concluded, with eighteen sorts of destruction effect. A confirming method of the worst section and a calculating method of the weight-bearing capability of main girders after destruction are also presented. |
