Abstract

An SMW wall was installed as a cutoff wall for seepage control during high floods in a narrow levee constructed in the early 1900's using sandy soils. After part of the wall was installed, difficulties were encountered in evaluating the permeability of the as-built cutoff wall according to the project specifications. Methods used to evaluate the permeability of the cutoff wall included laboratory tests on bulk samples and core samples and in-situ permeability tests. Significant differences in test results were caused by various sample preparation and handling procedures, sampling disturbance, and different testing methods. The difficulties were resolved by performing a trial mix study and installing a full scale test section that resulted in changed installation, sampling, and testing procedures.
