采用断裂力学方法计算老钢桥的剩余寿命，在确定初始裂纹尺寸、断裂临界裂纹 大小、交通荷载下构件受力以及裂纹扩展模拟四个方面作了详细的探讨。
Fracture mechanics method is used to calculate the remaining life of the old steel bridge, which is discussed in detail in four aspects: determining the initial crack size, the critical crack size, the component load under the traffic load and the crack propagation simulation.
