| Abstract: |
Three ferry docks are part of a ferry service which connect mainland Southwestern Ontario with Pelee Island, a 10,000 acre island situated in Lake Erie, approximately 30 km south of the mainland. A number of structural and operational deficiencies were identified at each of the ferry docks, and a rehabilitation strategy was developed to address these deficiencies. The existing sheet pile walls at the docks required strengthening to maintain their stability and structural integrity. To determine the strengthening requirements for the sheet pile walls, a mobilized earth pressure coefficient analysis was conducted. The strengthening and rehabilitation strategy developed through this analysis consisted of the installation of a caisson wall in front of the toe of the existing sheet piles below the dredge line, connected by a caisson cap beam. The rehabilitation of the ferry docks included providing scour protection and lowering the dredge line elevations. |
