介绍了一种通过桥梁截面转角来测挠度的方法，通过用辛普森数值积分法，由已知的转角算出梁的挠度，并在试验室内1根6 m 长的工字钢梁上进行了试验验证，同时对工程中各类常见桥型进行分析，表明该方法具有足够的精度，能够满足工程应用的要求。

A new method of deflection measurement through the bridge section angle is proposed in this paper,the deflection of the beam can be calculated by known angles using the Simpson’s method. Experimental verification of the method is studied on a 6 meters I-beam in the lab. The analysis of common bridge indicates that this method has enough precision and can meet engineering application requirements.
