Title: INSTRUMENTATION OF TRANSPORTATION EMBANKMENTS CONSTRUCTED ON SOFT GROUND
Accession Number: 00676521
Record Type: Monograph
Availability: Find a library where document is available Abstract: Economic considerations, aesthetics, or other factors often require that a highway embankment be constructed over soft, saturated soils. A high content of silt, clay, organics, and a high water table compound design and construction problems. Under these circumstances special treatment of the embankment materials and/or controlled construction procedures are warranted to ensure the safety and stability of the constructed embankment. Several methods are available to reduce the risk of an embankment failure during construction. These include the use of berms and vertical drains, surcharging, and staged construction. Geotechnical instrumentation is often a vital part of embankment construction under these circumstances to monitor field performance and provide information relevant to decisions regarding the rate of construction progress. The principal parameters monitored during embankment construction are pore water pressure and displacement, both vertical (i.e., settlement and heave) and lateral (shear). This Circular outlines the most commonly used instrumentation systems for these applications. It is intended as a general guide to the principles of operation and the application of these instruments for the field personnel or associated staff involved in installation, monitoring, and data analysis.
