Spatial Structure Characterization of the Soil Surrounding Buried Water Transmission Mains by Using a Sensor-Enabled Geotextile

Résumé

Close examination of the parameters that characterize the spatial variability of the soil is necessary to understand how this variability can be used to study the structural behavior of buried large-diameter water transmission mains. In this research, a sensorenabled geotextile was laid in a trench along a renewed water transmission pipeline segment to measure the ground strain during its installation and the first months of pipeline operation. A methodological approach was developed to identify, from experimental semivariograms built from ground strain measurement profiles, the scale of fluctuation that characterizes the horizontal spatial structure of the soil. Using both an experimental onsite test and a numerical model of the pipeline, the spatial variability was assumed to correspond to the soil modulus parameter in the model. The numerical results were well matched with the experimental test measurements. Both parameters, the scale of fluctuation and the soil modulus, were identified as important factors for understanding the spatial behavior of the soil-pipe system.
