Abstract : The rehabilitation of navigation structures requires consideration of the lateral earth pressures acting upon the structure. Typical assumptions for earth pressure loadings usually follow patterns dictated by classical theories. For example, at-rest pressures with a simple triangular distribution are often used. Although it has been known for some time that actual earth pressure distributions are more complex than this, in many cases it is expedient to use the simplest approach, and experience suggests that this approach is usually conservative. However, the problem of the navigation structures is one where the simplest assumption is not likely the best one, and because the assumed lateral pressures significantly impact the economics of rehabilitation, the problem deserves study under the Repair, Evaluation, Maintenance and Rehabilitation (REMR) research program.
