2 Terminology
2.u.1 Enclosing dikes seawall
A seawall built on one side facing the sea in a part of the sea area enclosed by the beach. 2.0.2 oulsanding bank
A seawall with two sides facing the sea that extends out from the coastline to the sea area, usually connected to the structure.
2.0.3 hippedestal
It is the top surface of the embankment set on the outside of the embankment slope to strengthen the embankment body. The platform is lower than the main spiral and is used to support the ball to go up.
2.0.4 limitheightofseawall refers to the maximum height of the foundation soil reaching the critical value of shear failure during the construction of the seawall.
2.t.5 concrete mushroom Stone blocks (pieces) are arranged according to certain requirements, exposed to a certain height, and embedded in the concrete embankment slope protection surface on site. They are shaped like "mushrooms", referred to as "mushroom stones". 3. Seawall design standards and regulations
