Abstract:

The Eisenhower and Snell Locks were constructed between 1955 and 1958 as part of an international cooperative effort to build the Saint Lawrence Seaway. In February 1990, the Saint Lawrence Seaway Development Corporation requested that the Corps of Engineers perform a structural evaluation study of these two locks to determine the adequacy of the existing locks considering present conditions and future needs, and to determine the advisability of their rehabilitation. The study focuses on the internal structural integrity of the chamber wall monoliths at each lock. The study consisted of three phases 1 Perform field tests and laboratory tests to determine the current state of the in situ concrete in the chamber wall monoliths and the concrete properties needed for the stress analyses 2 determine the state of stress within the chamber wall monoliths using nonlinear, two-dimensional, soil-structure interaction finite element analyses and 3 use dynamic finite element analyses of two monoliths to assess their structural integrity during earthquakes. To support the dynamic analysis, a geological seismological investigation was conducted to provide the ground motions, time histories, and corresponding response spectra that could be expected during a seismic event in the region.
