Luoyang Longmen Grottoes Rock-Cut Structure Monitoring
A Rock-Cut Structure Monitoring System case for Longmen Grottoes, focused on rock-mass fissure evolution, vibration response, displacement trend, weathering-related degradation, and nearby highway construction influence.
Project Type
Cultural Heritage Monitoring System
System Scale
East Hill grotto wall, West Hill Buddha area, entrance rock wall, burial-area rock wall, and long-term online monitoring platform
Data Output
rock fissure data, crack evolution trend, vibration response, displacement trend, weathering-related stability indicators, and alarm records
Engineering Value
How the system supported engineering decisions
The case is classified under Cultural Heritage Monitoring System instead of Civil Infrastructure Structural Monitoring.
The monitoring scope follows Rock-Cut Structure Monitoring terminology: rock-mass fissure evolution, weathering and structural degradation, vibration response, long-term stability, and human-activity influence.
The system configuration links sensors, acquisition hardware, TCP transmission, and PHM software into one RFQ-ready heritage monitoring package.
Monitoring Content
Monitoring scope and field constraints addressed by the deployment
Rock-mass fissure evolution monitoring was required above the grotto wall and around sensitive carved-stone areas.
Vibration response monitoring had to capture construction and human-activity influence without disrupting the protected site.
Long-term stability analysis needed displacement trend, weathering-related degradation indicators, and platform-based reporting.
System Configuration
Configured system architecture and data path
Field Devices
2D001 vibration sensors, crack gauges, displacement sensors, vibrating-wire channels, voltage channels, and protected field installation accessories
Communication Layer
DH5971N controller, vibrating-wire acquisition, voltage acquisition, TCP transmission module, and remote online data transfer
Central Platform
PHM / DL-SHM platform for rock fissure data, vibration response, displacement trend, long-term stability analysis, alarms, and reports
Case Visual Evidence
Source visuals and deployment references
Heritage monitoring system topology
Sensor, acquisition, communication, and software platform layers support online rock-cut heritage monitoring.
Long-term trend and warning platform

Project Overview
Engineering context and monitoring scope
In March 2025, a long-term monitoring system was arranged for Longmen Grottoes to evaluate how nearby highway construction could affect the stone cave structures. East Hill and West Hill monitoring used vibration sensors, crack gauges, displacement sensors, acquisition equipment, TCP data transmission, and a PHM intelligent maintenance platform.
