Abstract
In 1975, a dockwall at the Port of Milwaukee, Wisconsin failed as salt was being deposited behind the wall. In 1981, exploration at the site was required for a new development. The exploration program included field testing to measure the shear strength of the organic soils through which the failure occurred. Dutch cone and vane shear devices were used. Continuous undisturbed samples were obtained in two (2) borings. This allowed an accurate determination of the stratigraphy in the slide area. The shear strength of the undisturbed samples was measured in the laboratory by means of the Torvane device. The shear strength data were used in slope stability analyses using the STABL program. These analyses provided insight into the shear strength regime that would provide a factor of safety of unity. The shear strengths determined by the various methods are compared and discussed in light of the site stratigraphy.

A Dockwall Failure in Milwaukee, Wisconsin
In 1975, a dockwall at the Port of Milwaukee, Wisconsin failed as salt was being deposited behind the wall. In 1981, exploration at the site was required for a new development. The exploration program included field testing to measure the shear strength of the organic soils through which the failure occurred. Dutch cone and vane shear devices were used. Continuous undisturbed samples were obtained in two (2) borings. This allowed an accurate determination of the stratigraphy in the slide area. The shear strength of the undisturbed samples was measured in the laboratory by means of the Torvane device. The shear strength data were used in slope stability analyses using the STABL program. These analyses provided insight into the shear strength regime that would provide a factor of safety of unity. The shear strengths determined by the various methods are compared and discussed in light of the site stratigraphy.
