Partial Coefficient System for the Design of Monolithic Vertical Breakwaters Considering Sliding and Rupture Failure of the Foundation

The main object is to present a set of calibrated partial coefficients for monolithic vertical breakwater failure modes. A preliminary design of the monolithic breakwater will be considered, which will be designed from existing partial coefficients, documented in Eurocode 7 (1994). From this design a optimal reliability evaluation of the same structure is then performed using a level II FORM reliability analysis, by fixing the safety index, thus altering the preliminary design by increasing or reducing the chosen partial coefficients. The method of nprobabilistic foundation stability analysis is presented by the example of a translation slip failure involving kinematically correct slip surfaces and failure zones in friction based soil. A conventional quasi-static analysis is used.
