Project Background

The construction and operation environment of railway tunnels is complex. Affected by geological conditions, construction methods, support structures, groundwater and changes in the surrounding environment, tunnel structures may experience varying degrees of settlement and deformation. For the Shenzhen-Shanwei Railway tunnel settlement monitoring project, timely, continuous and accurate knowledge of settlement changes at key locations is an important basis for ensuring construction safety and structural stability.

Traditional manual measurement has problems such as limited frequency, high intensity of on-site work and insufficient data continuity. To meet the tunnel settlement monitoring needs, the project introduced the Haytham online visual tracker to achieve long-term automated monitoring of key measurement points.

Solution

Haytham online visual trackerPassive targets are arranged at key positions of the tunnel structure, and the visual acquisition equipment continuously tracks changes in target positions. Combined with digital image correlation (DIC) algorithms and subpixel positioning technology, the tunnel settlement and displacement changes are calculated.

The system supports remote data viewing: monitoring data can be uploaded to the cloud platform, forming displacement trend curves, historical records and abnormal change information. Managers can intuitively grasp the changes of the tunnel structure through the platform, providing data reference for safety judgment and risk handling during construction.

Application Value

In this project, Haytham online visual trackerIt achieves non-contact monitoring of tunnel settlement changes, reducing the workload of repeated manual on-site measurement and lowering operational risks in complex construction environments. The system can continuously track multiple measurement points, helping project personnel understand structural change trends in time.

Online visual monitoring not only provides numerical settlement data but also retains image information, making monitoring results more intuitive and traceable. For long linear and complex projects such as railway tunnels, the online visual tracker can improve monitoring efficiency and data management capability, providing reliable support for engineering safety management.

Applicable Scenarios

Haytham online visual trackerApplicable to engineering safety monitoring scenarios such as railway tunnel settlement monitoring, metro tunnel deformation monitoring, bridge displacement monitoring, foundation pit support monitoring, slope displacement monitoring and dam structure monitoring。
