【摘要】 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。更多还原

【Abstract】 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.更多还原
