Abstract

The rational design diagram for Dolos armour should incorporate both the hydraulic stability and the structural integrity. The previous tests performed by Aalborg University made available such design diagram for the trunk of Dolos breakwater without superstructures (Burcharth et al 1992). To extend the design diagram to cover Dolos breakwaters with superstructure, 2-D model tests of Dolos breakwater with wave wall were done. Furthermore, Task IA will give the design diagram for Tetrapod breakwaters without a superstructure .. The more complete research results on Dolosse can certainly give some insight into the behaviour of Tetrapods armour layer of the breakwaters with superstructure. The main part of the experiment was on the Dolos breakwater with a high superstructure, where there was almost no overtopping" This case is believed to be the most dangerous one. The test of the Dolos breakwater with a low superstructure was also performed". The objective of the last part of the experiment is to investigate the influence of the method of placing and packing the blocks on the hydraulic stability. The Dolosse were more carefully put on the slope and the hydraulic stability of such slope was compared with that of the more randomly packed slope. The whole experiment was carried out in the period of August - November 1993 The analysis on the hydraulic stability has been finished while the stresses analysis is under way.
