Tunnel Convergence Monitoring Cases隧道收敛监测案例
Tunnel convergence monitoring focuses on cross-section deformation. Flexible arrays can follow curved installation paths and form convergence rings, while laser and settlement sensors provide independent checks.隧道收敛监测关注断面变形。柔性阵列可顺应曲线安装形成收敛环，激光测距与沉降传感器提供独立校核。
Flexible arrays support ring-type installation around tunnel sections.柔性阵列支持沿隧道断面环形布设。
Segmented sensors convert bending shape into displacement profiles.分段传感器把弯曲形态转换为位移剖面。
Laser rangefinders can track key chord lengths in the same section.激光测距仪可监测同一断面的关键弦长。
Section deformation is judged by trend, rate and construction stage.断面变形按趋势、速率和工况阶段共同判断。
What Rasber Monitors On Site瑞茨柏在现场监测什么
Tunnel convergence is different from vertical borehole inclinometry. The monitored object is a curved lining or excavation section, so the sensor must tolerate bending and installation geometry. Rasber uses flexible inclinometer arrays for profile continuity, laser rangefinders for point-to-point confirmation, settlement sensors where vertical movement matters, and an edge terminal to package all readings into one cross-section record.隧道收敛不同于竖孔测斜。被测对象是弯曲的衬砌或开挖断面，因此传感器必须适应弯曲和安装几何。瑞茨柏用柔性测斜阵列保持剖面连续性，用激光测距校核关键点间距离，在需要时叠加沉降传感器，再通过边缘终端把所有数据组织为同一断面记录。
- ✓Geometry-aware installation按断面几何安装
Flexible arrays are selected when the path is curved, horizontal or ring-shaped rather than a straight vertical casing.当路径为曲线、水平或环形，而非竖直测斜管时，优先使用柔性阵列。
- ✓Cross-section rather than single point关注断面而非单点
The warning object is the shape change of the section, not just one displacement value.预警对象是断面形态变化，而不只是某一个位移值。
- ✓Independent checks reduce false judgement独立校核降低误判
Laser distance, settlement and construction event records help separate real convergence from installation disturbance.激光距离、沉降和工况记录帮助区分真实收敛与安装扰动。

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 |
|---|---|
| Section definition断面定义 | Define convergence section, sensor arc, laser chord and settlement reference before installation.安装前明确收敛断面、传感器弧线、激光弦长和沉降基准。 |
| Fixing method固定方式 | Keep the array attached to the lining or support structure without local kinks.确保阵列贴合衬砌或支护结构，避免局部折弯。 |
| Data interpretation数据解释 | Read section shape, point displacement and construction event together.联合读取断面形态、点位移和施工事件。 |
