Where scour is considered to be likely, protection, such as a rubble anti-scour apron on the seabed, should be provided in front of quay walls and particularly at berths where vessels will generally berth in the same position.

The toe of the wall over the length of the dispersed load should have an adequate bearing capacity, which might require that the wall be taken down to rock. The possibility of impact damage in the area of joints during placing of the units should be taken into account. According to the classes of vessel expected, fuel oil, marine gas oil, marine diesel oil and intermediates might be required.

The vertical actions are supported by the embedded retaining wall and the bearing piles. If the seabed is sandy, a ilter layer of graded gravel should be placed between the rubble and subsoil to minimize settlement into the seabed.

Figure 1 Soldier-piled wall: The recommendations in 6. The resistance of wall hs to overturning resulting from pull-out should be checked. Figure 17 shows typical examples of each type. These stresses in steel 6349-22 timber elements should be based on the wall section at the end of the design life. It should not be quoted as if it were a speciication and particular care should be taken to ensure that claims of compliance are not misleading.

Separation between underside of relieving slab and top surface of material beneath is beneicial to assist in preventing pressure from the slab being exerted on the material below. In addition, passing vessels generate waves, although the period of such waves is 63492 too short to apply signiicant loads to a wall.

The materials that are needed to achieve durability are described in BS Many types of quay structure that retain the ground behind them yield slightly during or after construction, with the development of active soil pressure and passive resistance. The effects of differential settlement may be partially accommodated along the inclined slip planes.

The choice of structure should take 649-2 account the need to protect the works during construction against damage caused by loating craft, waves and currents. On the seaward face, where the bedding might be disturbed by currents or propeller action, it should be protected by an anti-scour apron. A deeper wall is required to achieve ixity in the ixed-earth condition, but in a free-earth condition the shallower penetration required for 6349- alone has to be increased to provide adequate resistance to forward movement.

Deck units to be placed on piles should be designed to accommodate the permissible deviation in the piles.

The effects of earthquakes on stability in accordance with BS EN should be taken into account. Inclined anchor piles should be designed such that soil resistance is obtained only outside the active wedge, in the same way as grouted anchors. Provision should be made to prevent loss of ine material through the joints. If the structure is delected by hydraulic ill, it might not be able to yield suficiently to allow the subsequent development of active pressures.

At some ports there is a demand for the bunkering of ships. The durability of a structure should take account of the effects of the agreed operation and maintenance strategy see 4.

Blocks are provided with a tongue-and-groove interlock. They can be built in most types of soil and may be toed or dowelled into solid rock, but are generally unsuitable where lowing or artesian water is present during construction.

Code of practice for the design, construction and maintenance of straight stairs and winders BSCode of practice for earthworks BS Fuel hydrants served by buried pipelines should be provided at convenient locations.

Where a combined section is required to resist horizontal actions, the same load-bearing elements may be used to carry the vertical actions. 66349-2 tolerances typically 0.
