Dam and Urban Structural Response Monitoring
A seismic monitoring case group covering dam strong-motion arrays, earthquake intensity review, automatic event reports, GNSS deformation logic, and remote network transmission.
Project Type
Civil Infrastructure Structural Monitoring
System Scale
dam strong-motion arrays, free-field stations, remote transmission, and city-level seismic data review
Data Output
earthquake event waveform, intensity, peak acceleration, displacement, duration, station status, GNSS deformation trend, and automatic reports
Engineering Value
How the system supported engineering decisions
The case strengthens DL-SE positioning without adding any new public product family.
Dam strong-motion monitoring and city seismic network workflows are expressed as event detection, reporting, and remote station management capabilities.
GNSS plus acceleration context supports broader seismic and deformation safety interpretation.
Monitoring Content
Monitoring scope and field constraints addressed by the deployment
Dam structures required measurement points at crest, gallery, foundation, free-field, and key structural sections.
Earthquake events required automatic trigger, event file storage, intensity calculation, peak acceleration review, displacement calculation, and report generation.
Remote station networks needed reliable timing, data transmission, station health review, and integration with GNSS or deformation monitoring logic.
System Configuration
Configured system architecture and data path
Field Devices
DL-VIB strong-motion and seismic instruments, DL-GN displacement stations, and field timing or communication devices
Communication Layer

Hydropower station field site
The monitoring system is deployed around dam galleries, plant structures, and protected field stations where event data is transmitted back to the monitoring center.
Strong-motion sensor mounted on concrete base
A protected accelerometer installation captures structural response at dam or gallery measurement points.
Triaxial force-balance accelerometer station
Three-component acceleration measurement supports earthquake waveform, peak acceleration, displacement, and duration analysis.
Protected free-field or reference station
Field stations provide reference ground motion data for comparison with dam crest, gallery, foundation, and structural response points.

Protective rails and barriers keep outdoor seismic instruments and cabling stable in exposed hydropower station environments.
Monitoring center acquisition racks
Centralized racks receive multi-point strong-motion data and support event trigger, station status review, alarm delivery, and report generation.
Cabinet-mounted data acquisition unit
Rack-mounted acquisition equipment links field accelerometers to the engineering seismic monitoring platform.
On-site installation inside dam structure
Gallery-side installation work covers sensor fixing, cable routing, and protected wiring for long-term strong-motion monitoring.
