摘要
阐述了使用精密水准方法进行桥梁挠度测量的基本原理,结合工程实例比较了3种精密水准挠度观测方法的精度,证明了精密水准方法进行桥梁挠度测量的优点和实用价值.
The measuring principle of bridge deflection is set forth by using precise levelling method; and the accuracy of three kinds of precise levelling methods for bridge deflection are compared according to the testing results in situ. It is confirms that making use of the precise levelling method to measure the bridge deflection has a great deal advantages and useful values.
