Monitoring Foundation Soil Vital Signs

Geotechnical instrumentation allows engineers to track the vital signs of the underlying soils, helping optimize construction project schedules while managing risks associated with settlement and stability. This article provides an overview of some of the tools that are used in geotechnical instrumentation. Inclinometers measure horizontal movement of soil, and can show not only how much movement is occurring, but also the depth at which the movement is occurring. This allows engineers to carefully monitor soft layers. Settlement cells measure the settlement of soil supporting an embankment. Piezometers measure the pore pressure within the soil. Both piezometers and settlement cells can be used to double check expected settlement, which is often critical to construction schedules. The article highlights two recent bridge projects where inclinometers, settlement cells and piezometers were used to save time. Both projects involved the construction of bridges over soft, interbedded silts and clays, and both benefited from geotechnical instrumentation.
