Geotechnical Instruments in Structural Monitoring
نویسندگان
چکیده
Geotechnical instruments are used widely as a complementary tool to geodetic methods in monitoring natural and man-made structures. This paper provides an overview of geotechnical instruments used in structural monitoring. The transducers commonly used in geotechnical instrumentation are first introduced. This is followed by an introduction of the various types of instruments including their working principles and applications. The advantages and disadvantages of geotechnical instruments when compared with geodetic methods in structural monitoring are finally discussed.

The Application of GPS To Dam Surface Monitoring
Dam monitoring relies on the long-term measurement of small structural motions at regular intervals. Traditional surveying techniques and geotechnical instrumentation can effectively monitor oneor twodimensional modes of motion. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, whilst ...
متن کاملReducing performance uncertainties with monitoring data
In this research, a new method is proposed to update system reliability based on data recorded by instruments and sensors installed on geotechnical systems to reduce uncertainties. The method is founded on Bayesian analysis and Monte Carlo simulation and is capable of estimating the functional relationship between the updated failure probability and the monitoring value. It is shown that as lon...

متن کاملPercussive Dynamic Cone Penetrometer for Geotechnical Surface Assessment with a Planetary
Introduction: During the past planetary surface missions, few instruments have been deployed to directly assess soil physical properties like density, soil strength (internal friction and cohesion), and pressure/sinkage curves, or their spatial variation. Several Soviet lunar missions were equipped with small cone vane penetrometers, and the Apollo astronauts also used two different manual pene...
