MIL-HDBK-1025/5
2) Cellular steel sheet pile structure for less severe
exposure.
Other breakwater types include:
c)
1) Timber structure.
2) Steel structure.
3) Concrete sheet pile structure.
4) Masonry block structure.
5) Composite structures.
Sand-filled sheet pile structure.
6)
7) Structure consisting of prefabricated concrete cells set
side by side and securely fastened together.
8) Concrete superstructure built on a submerged rubble base.
9) Perforated Swiss-cheese breakwater, which partially
dissipates wave energy in a chamber behind a perforated wall (see Figure 23).
Rubble-Mound Construction
2.5.2.6
Dimensional Features
a)
1) Armor stone size and slope of primary cover layer.
2) Crest elevation.
3) Crest width.
4) Underlayers and core.
5) Layer thicknesses.
6) Bedding or filter layer, and its size and thickness.
Construction Factors:
b)
1) Integrity of a rubble-mound breakwater is largely
dependent on the stability of the stones and armor units of which it is built.
2) The toe of a rubble-mound structure in water shallower
than about twice the design wave height may be subjected to severe scouring
currents caused by wave turbulence. Bedding layer shall be carried well
beyond the toe stones.
3) The bedding layer and internal layers of smaller stone
sizes shall be placed before the armor layer is installed.
