Stability and Stress Analyses, Marseilles Dam, Illinois Waterway
The monoliths of Marseilles Dam were analyzed to see if they meet present-day stability requirements. In the analysis of the tainter gate monoliths, the keys connecting the pier and spillway sections were determined to be overstressed; therefore, the spillway and pier sections were considered to act independently. Using this assumption, the pier and spillway sections were analyzed independently for stability considering the following load cases: (1) Normal operation; (2) Normal operation with ice; (3) Normal operation with earthquake; and (4) Flood condition. The results showed that the spillway sections were adequate in stability, and the pier sections were inadequate against overturning. To correct the inadequacy of the pier sections, it was recommended that each pier section be posttensioned using a 602-kip force. The pier sections were reanalyzed to include the recommended posttensioning and were determined to be adequate in stability. The resulting stresses in the structure, foundation, and grouted anchors were computed and determined to be within allowables. A previous stability investigation by the U. S. Army Engineer District, Chicago, concluded that the stability of the ice chute monoliths was adequate. This paper concurs with that conclusion. (Author)
