Description:

This course reviews the applicability of the wide range of specialty geotechnical construction techniques used in rock and soil foundations under dams and levees. These techniques are employed to provide seepage reduction and improve soils susceptible to seismicity or are otherwise too weak to sustain embankment rebuilding projects. The world of grouting alone is very wide, ranging from rock fissure and void grouting to permeation and compaction grouting in soils. The Deep Mixing Methods (DMM) are similarly diverse and are used to form cut-offs and shear panels for both seismic and static improvements. So-called “positive” cut-off walls are constructed by several methods, including the use of clamshells, hydromills, and secant piling. Each of these techniques is described, illustrated by major U.S. dam and levee remediation case histories.
