Retaining Wall & Slope Structure Monitoring
Services
Service Overview
RST Ltd. provides retaining wall and slope structure monitoring services, using inclinometers to measure angular changes and deep-layer horizontal displacement of the wall and backfill, optionally paired with GNSS to measure 3D displacement at the wall top. This captures the stability of retaining structures and the lateral deformation that occurs during deep excavation.
Applicable Scenarios
- Retaining walls along roads and on hillsides
- Diaphragm wall / soldier pile support for deep excavation projects
- Protection of adjacent buildings and construction risk control
- Long-term monitoring of slope lattice beams and retaining structures
Monitoring Methods
- Technologies used: inclinometers for multi-depth horizontal displacement, GNSS for 3D displacement of the wall top
- Measurement items: wall tilt, deep-layer horizontal displacement profile, wall top displacement
- Accuracy specifications: inclinometers support simultaneous multi-depth measurement; GNSS at centimeter level
- Data transmission and visualization: Data is transmitted to the GeoGuard platform with real-time alerts
Comparison with Other Methods
| Item | Inclinometer | GNSS | Manual measurement |
|---|---|---|---|
| Measurement target | Deep-layer horizontal displacement | 3D surface displacement | Surface |
| Continuity | Can be continuous | 24-hour continuous | Periodic |
| Excavation process monitoring | Well-suited | Supplementary | Limited |
| Best for | Deep-layer deformation | Wall top displacement | Spot checks |
Inclinometers and GNSS are frequently used together to capture both surface and subsurface deformation.

Frequently Asked Questions
What does retaining wall monitoring typically measure?
The focus is on wall tilt and displacement. We use inclinometers to measure angular changes and deep-layer horizontal displacement of the wall and backfill, optionally paired with GNSS to measure 3D displacement at the wall top, capturing the stability of the retaining structure.
Can the retaining support of deep excavation projects also be monitored?
Yes. In deep excavation, multi-depth inclinometers are often embedded in diaphragm walls or soldier piles to monitor lateral deformation during excavation; combined with real-time alerts, this helps control the safety of adjacent buildings and construction risk.
How deep can inclinometers measure?
Inclinometer systems support simultaneous multi-depth measurement, with sensor rings installed at various depths per the design to perform deep-layer horizontal displacement profiling along the casing axis; the depth is configured according to engineering requirements and ground conditions.
