Bridge Construction Stage Cable Replacement Monitoring
A construction-stage monitoring workflow for cable replacement, cable tension adjustment, strain calibration, and cloud-access structural status supervision.
Project Type
Civil Infrastructure Structural Monitoring
System Scale
distributed bridge construction monitoring with 24 strain points, 14 cable-force sensors, 4G transmission, and cloud access
Data Output
cable force, support-node strain, tension adjustment trend, construction-stage status, and remote monitoring records
Engineering Value
How the system supported engineering decisions
The case adds construction-stage monitoring to the civil infrastructure vertical.
DL-SEN strain and cable-force sensors with distributed DL-DAQ systems supported cable replacement and tension adjustment decisions.
4G and cloud-connected DL-SHM monitoring provided remote visibility during bridge construction work.
Monitoring Content
Monitoring scope and field constraints addressed by the deployment
Cable replacement required real-time tracking of cable force and deck support strain during construction-stage adjustment.
Measurement points were dispersed across the bridge, so acquisition equipment had to be placed close to sensors for practical wiring.
Project stakeholders needed remote access to construction-stage data through 4G and cloud monitoring.

Project Overview
Engineering context and monitoring scope
A city bridge required cable replacement because aging stay cables affected service life. Strain sensors were installed at bridge deck support nodes and cable-force sensors were installed on replacement cables. Distributed acquisition stations were placed near dispersed measurement points, with 4G communication sending monitoring data to a cloud server for user access and status review.
