What Rasber Monitors On Site瑞茨柏在现场监测什么
Deep excavations fail through coupled mechanisms: retaining-wall movement, delayed support installation, groundwater drawdown, support-force redistribution and nearby settlement. Rasber treats these as one project rather than separate instruments. The in-place inclinometer provides high-frequency deep displacement curves; vibrating-wire terminals track support force and structural stress; water-level gauges confirm dewatering effects; the cloud platform links each threshold to the excavation stage.深基坑风险不是单一传感器能解释的：围护墙变形、支撑架设滞后、降水效果、支撑轴力重分布和周边沉降会互相影响。瑞茨柏把这些量作为同一个项目系统处理：固定式测斜仪提供高频深层位移曲线，振弦终端跟踪支撑轴力和结构应力，水位计复核降水效果，云平台把每一条阈值和开挖工况绑定起来。
- ✓Retaining-wall profile, not only surface movement不只看表面位移，要看围护墙管形
IPI strings are installed in inclinometer casings so engineers see displacement by depth, including kick-foot and support-induced inflection shapes.固定式测斜仪布设在测斜管内，按深度输出变形曲线，可识别踢脚、支撑内凹等工况特征。
- ✓Support-force monitoring during rapid construction快速施工阶段的支撑轴力监控
VW load cells and 16-channel terminals make support-force changes visible during concrete support and steel support stages.振弦轴力计与 16 通道采集终端用于混凝土支撑、钢支撑阶段的轴力变化跟踪。
- ✓Alarm logic tied to excavation stage报警逻辑绑定开挖阶段
The same displacement value can mean different risk at different stages; cloud thresholds are configured by rate, cumulative value and current construction state.同一个位移值在不同开挖阶段风险含义不同，云端阈值按速率、累计值与当前工况共同配置。

These cases focus on monitoring targets, sensor combinations and the data logic used after delivery.以下案例重点展示监测对象、传感器组合和交付后的数据逻辑。
Hangzhou Metro Line 3 Chaowang Road Station杭州地铁 3 号线潮王路站
From 2021-08-12, automated points CX4/CX5 were deployed for emergency monitoring. The ZQT1 warning point reached a 2.96 mm/d rate and 8.87 mm cumulative displacement at 7.0 m depth; the recommendation was to install steel support and apply axial force while increasing monitoring to at least twice per day.2021 年 8 月 12 日起，现场布设 CX4/CX5 自动化测点用于抢险监测。ZQT1 在 7.0m 深度变化速率达到 2.96mm/d，累计位移 8.87mm；预警建议为及时架设钢支撑并施加轴力，同时加密监测不少于每日 2 次。

High-frequency pit monitoring captured periodic motion linked to tidal response. This is the type of slow, repeated signal that weekly manual measurement usually misses.高频基坑监测捕捉到与潮汐相关的周期性变形，这类缓慢重复信号通常难以被周度人工测量发现。
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 |
|---|---|
| Before installation安装前 | Confirm expected deformation direction, casing depth, support schedule and alarm thresholds.确认预期变形方向、测斜管深度、支撑架设计划与报警阈值。 |
| During excavation开挖中 | Watch displacement profile, rate change, support force, water level and construction event log together.联合查看管形曲线、变化速率、支撑轴力、水位与工况记录。 |
| After alarm预警后 | Check physical construction state before interpreting the data as pure structural movement.先核对现场支撑和开挖状态，再判断数据是否为真实结构变形。 |
