Bridges

Bridge structures in many countries around the world have used Geokon sensors for measuring key parameters such as strain, displacement, force, temperature, inclination, alignment and settlement. Sensors are installed permanently for long-term health monitoring, temporarily for load testing and/or to ensure safe working conditions during repair or strengthening. Internet-accessible data acquisition systems ensure that any significant change in the condition or behavior of the structure is logged, reported and efficiently monitored.

Case Histories

Kao Ping Bridge

South Taiwan

The new Kao Ping Bridge is one of the longest (510 m) and the highest (183.5 m) bridges in Asia. Construction of the bridge began in February 1997 and ended in February 2000. Instrumentation included Strain Gages in the concrete and steel segments.

Marbella Relief Road Viaduct

Marbella, Malaga, Spain

In 1997, a landslide occurred in Malaga, Spain, which caused the piers of the Marbella Relief Road Viaduct to tilt. To monitor the ongoing safety of the viaduct, eight vibrating wire Biaxial Tiltmeters were installed at the base of each pier.

Point Marion Bridge

Pennsylvania, USA

A new bridge is being built 20 m south of the historic Point Marion Bridge, which will be replaced due to its structural deficiencies.

The soft nature of the surrounding foundation soils prompted a geotechnical / structural instrumentation program to monitor the impact of new bridge construction on the aging structure. Automated measurements were taken of 19 Vibrating Wire Piezometers to monitor water pressures in the foundation soils on both sides of the river. In addition, a Vibrating Wire Piezometer was used to record river water levels, and two Vibrating Wire Strain Gages were used to monitor the old bridge. Manual measurements were taken of Tilt Plates, settlement pins (placed in the fill) and Inclinometers installed in the foundation soils.

Data were automatically collected and imported into an MultiLoggerDB database on an hourly basis. MLWeb software was then used to provide the construction contractor and owner with access to data via the Internet.
