Abstract : Drilling for laboratory testing of soil, concrete, and rock was accomplished as part of a major rehabilitation program at Dresden Island Lock and Dam, Illinois Waterway. This report covers the work accomplished during the Dam, Illinois Waterway. This report covers the work accomplished during the Phase II program entitled 'Compliance and Scour Detection'. The purpose of the compliance work was to determine selected materials properties and to develop engineering design parameters related to materials found at the site that were different than previously found and tested. A secondary purpose of the compliance work was to determine the base elevation of the head-gate and tainter-gate dams. The scour detection work was accomplished to determine depth of possible scouring behind the tainter-gate dam and undercutting of the downstream apron and piers. Samples of critical clay and shale seams were obtained and tested. The base elevation of the head gates was 18 ft deeper than shown on the original working drawings, the base elevation of the tainter-gate section was 7 to 9 ft deeper than shown on original drawings. Local undercutting of the tainter-gate apron exists; however, the dam proper is not undercut. No covered scoured areas were detected behind the dam. A study of the foundation condition was made. Normal faulting was interpreted to exist beneath the lock and dam. (Author)
