摘　　要：为了对现役桥梁进行正确的状态评估,并对出现的损伤状况进行识别,文中基于有效独立法研究了传感器的优化布置,并采用柔度差法模拟了损伤识别情况。通过算例验证了该方法的有效性。In order to give a proper assessment to the active duty bridge and recognize the situation of damage appears. This article optimizes the sensor placement based on the study of effective independ- ence method, and use the flexibility difference method to simulate the damage detection. Finally, the effectiveness of this method is verified by an example.
