Industrial Park Retaining Wall Safety Monitoring

A key retaining wall in an industrial park has seen its structural integrity gradually threatened by long-term environmental effects and construction disturbance. As the instability of the slope intensifies, the cracking and deformation of the wall have become increasingly prominent, and the potential risk keeps escalating. According to the on-site assessment, the damage to the retaining wall structure was at a moderate level, but the surrounding environment is complex and a large-scale slope slide could be triggered at any time, seriously endangering the safety of nearby buildings and personnel. Facing this severe challenge, timely and precise monitoring is particularly important.

To address the safety hazards of the retaining wall, the Haytham online visual tracker was adopted for 24-hour uninterrupted monitoring. Through the internationally leading oblique optical axis DIC technology and sub-pixel positioning algorithms, the device tracks the subtle displacement and deformation of the wall in real time.

According to the project requirements and the complexity of the site environment, the monitoring team deployed monitoring points at 12 key locations on the retaining wall. These monitoring points cover parameters such as the horizontal displacement, vertical displacement and inclination of the wall. Through automated data acquisition and analysis, the monitoring system achieves all-round, three-dimensional monitoring of the wall structure. Monitoring targets were specially installed at the cracks to capture dynamic data on crack propagation more accurately.

Through the 24-hour online monitoring platform, managers can view the change data of every monitoring point in real time, and the system automatically generates alarm information to ensure early warning at the first moment of any anomaly. This efficient and precise monitoring system provides on-site personnel with a timely basis for decision-making, significantly improving the efficiency of emergency response.
