Installation of a Seepage Cutoff Wall at the Herbert Hoover Dike Using the Cutter Soil Mixing Method
The Herbert Hoover Dike (HHD) was originally constructed as a series of embankments around Lake Okeechobee from 1915 through the 1970's to provide flood protection to the surrounding communities and controlled irrigation for local agriculture. A cutoff wall design was presented by the U.S. Army Corps of Engineers (USACE) as the preferred alternative to reduce seepage and piping observed along the dike alignment. The seepage cutoff wall has been designed to penetrate through the highly transmissive limestone layer down into the underlying and less transmissive silty sand. The USACE's acceptance criteria for the cutoff wall includes demonstration of the homogeneity and continuity of the in-place cutoff wall material, average unconfined compressive strengths of between 100 and 500 psi on core samples, and a field permeability of equal to or less than 1 x 10-6 centimeters per second (cm/s). Cutter Soil Mixing (CSM), one of three implemented technologies, has been used to successfully complete approximately 18,000 linear feet of seepage cutoff wall to a depth of approximately 70 feet. In collaboration with BFC, Geosyntec Consultants developed a GIS application titled "WallTracker" to manage, visualize and remotely access in near-real time, data from the HHD project. This paper was prepared to achieve three primary objectives: briefly introduce the challenges associated with construction of the HHD cutoff structure; describe the use of CSM technology to address these challenges; and present the capability and functionality of the WallTracker GIS application to address USACE's information requirements.
