Sheet Pile Wall Design

Generally in sheet pile wall design, normally we need to calculate all kinds of loads, scour depth, length of sheet pile (including pile embeded depth, the concrete cover thickness) through test algorithm. According to different construction conditions in process aselect sheet pile sections, supporting layers and structure, at last check the overall stability of sheet pile wall.

1. Data Collection
Collect and analyze geological maps, the highest water level, the highest level of construction and so on.

2. Determine Geometry Size
Plane size is often dermined by upper structure and its foundation size. Sheet pile wall construction should be in accordance with the whole project construction and template installation, so the wall’s size should be at least 1.5m greater than the basic outline. It must also consider the needed size of pumping equipment and wells’ installation.

Dimensional size is usually influenced by water level, scour depth, the depth of excavation inside wall and factors such as stability in the pit end. But the most direct impact is water level.

3. Calculate Sheet Pile Wall Lateral Pressure

Assume sheet pile’s embedment depth first, then calculat lateral pressures hydrostatic pressure, water impact, ice pressure, wind, wave power and earth pressure.

4. Force Checking by Constructin Conditions

5. Stability Checking
Need to analyze wall’s overall stability and soil stability at the end of the foundation such as arch, water well-out and sand-cast.
