In case where the bulkheads, which surround a reclamation area for waste disposal, are required to prevent substances contained in waste leaking out to the sea, they are constructed as waterproof structures.
For a caisson-type bulkhead, waterproof sheets are mostly placed in the backfill space for this purpose. Because wave-driven pressure, which propagates through nibbles mound and backfill, acts on thesheet, weight is placed on it to prevent its movement and failure.
In this study, we conducted a laboratory experiment and numerical analysis to clarify the characteristics of the dynamic pressure, which leads to the development of the design method for this kind of structure.
