倾斜传感器在高墩桥墩顶位移监测中的应用

墩顶位移是表征高墩桥桥墩安全的重要参数之一。文中分析了倾斜传感器测量墩顶位移的原理，并以重庆市向家坡立交桥监测系统为例，应用倾斜传感器对该桥Ⅳ匝道10号桥墩的墩顶位移进行了长期监测，根据实际获得的监测数据，分析了该桥墩墩顶在桥梁运营过程中的变化，初步讨论了环境温度的变化对桥墩结构变形的影响。

Application of Tilt Sensor to Displacement Monitoring of High Piers

The pier displacement is a key parameter for analyzing the security of the high pier bridges. A novel method which can indirectly measure the pier displacement with tilt sensor is presented and experimented in the monitoring system for the No. 10 pier of Xiangjiapo Over-Bridge in Chongqing City of China. Through a long-period monitoring, much data are gained and some analyses about the change of the pier displacement effected by the environment temperature have done.
