Bridge Structural Health Monitoring Cases桥梁结构健康监测案例
Bridge monitoring connects slow geometry change with traffic, wind, temperature and support conditions. The project stack uses GNSS, level gauges, tilt, stress sensors, vibration and weather data to support lifecycle maintenance.桥梁监测要把缓慢几何变化与交通、风、温度、支座和基础状态连接起来。项目组合使用 GNSS、水准、倾角、应力、振动和气象数据支撑全生命周期养护。
Main towers, piers and critical points can be tracked in north-east-up displacement.主塔、桥墩和关键点可按三维位移跟踪。
Hydrostatic level gauges support high-resolution elevation trends.静力水准仪支持高分辨率高程趋势。
Wind, temperature and rainfall explain part of structural response.风、温度和雨量可解释部分结构响应。
Trend-based monitoring supports maintenance planning rather than one-time inspection.趋势监测用于养护决策，而不是一次性检测。
What Rasber Monitors On Site瑞茨柏在现场监测什么
Bridge structural health monitoring must separate normal environmental response from damage-related change. GNSS tracks large-scale tower and deck geometry; hydrostatic levels track settlement and elevation differences; tilt and vibration sensors capture local response; VW sensors monitor stress where embedment or anchorage allows; weather stations provide wind, rainfall and temperature context for every alarm.桥梁结构健康监测必须区分正常环境响应和损伤相关变化。GNSS 跟踪主塔、桥面等大尺度几何变化，静力水准仪跟踪沉降和高程差，倾角与振动传感器捕捉局部响应，振弦传感器监测可预埋或可锚固部位的应力，气象站为每一次报警提供风、雨、温度背景。
- ✓Geometry plus environment几何变化结合环境
Displacement, settlement and tilt curves are reviewed against wind, rainfall and temperature instead of judged in isolation.位移、沉降和倾角曲线与风、雨、温度同步复核，而不是孤立判断。
- ✓Pier and foundation focus重点关注桥墩与基础
GNSS, level gauges and inclinometers can be configured around piers, pile foundations and slopes near bridge approaches.GNSS、水准和测斜可围绕桥墩、桩基和桥头边坡配置。
- ✓Operational maintenance view运营养护视图
The cloud platform turns long-term data into trend, alarm and inspection records for bridge owners.云平台把长期数据转成趋势、报警和巡检记录，服务桥梁业主养护。

Delivery Checks Behind Reliable Data可靠数据背后的交付检查
The following checks are standard items in field delivery and long-term operation.以下检查项是现场交付和长期运行中的标准动作。
| Delivery phase交付阶段 | Field check现场检查项 |
|---|---|
| Reference frame基准框架 | Define stable reference points before interpreting bridge displacement.先定义稳定基准点，再解释桥梁位移。 |
| Environmental baseline环境基线 | Build temperature, wind and traffic context into the analysis period.在分析周期中纳入温度、风和交通背景。 |
| Owner reporting业主报告 | Summarize trend, alarm events and inspection actions in one lifecycle record.将趋势、报警事件和巡检动作合并为一份生命周期记录。 |
