Reliability-based assessment and design of stone-filled crib seawalls for shoreline protection

摘要

In this study, an efficient reliability-based design tool for stone-filled crib seawalls is developed. The first-order reliability method is integrated into spreadsheet to facilitate the reliability analysis for practical application. Using this spreadsheet tool, the effects of several major uncertain factors on the seawall design, including design water level, material property, and wave forces, are explicitly explored. In addition, the impact of progressive scour on the seawall stability is demonstrated through a time-dependent reliability analysis. This developed reliability-based design tool for seawalls is validated through comparing with the Monte Carlo simulation. This seawall design tool is easy to use and can be readily adapted in various aspects in the seawall design for shoreline protection.
