NOTES:
1. SOLDIER PILE EMBEDMENT DEPTH “D” SHOULD CONSIDER NECESSARY VERTICAL CAPACITY, KICKOUT, AND
OVERTURNING RESISTANCE.
2. PASSIVE PRESSURE INCLUDES A FACTOR OF SAFETY OF 1.5.
3. DIAGRAM DOES NOT INCLUDE HYDROSTATIC PRESSURES AND ASSUMES WALLS ARE SUITABLY DRAINED TO
PREVENT BUILDUP OF HYDROSTATIC PRESSURE.
4. DIAGRAM IS ILLUSTRATIVE AND NOT REFERENCED TO A PARTICULAR LOCATION.
5. LAGGING MAY BE DESIGNED USING 50 PERCENT OF THE ACTIVE EARTH PRESSURE.
6. SLOPE ABOVE SHORING WALL SHALL BE NO STEEPER THAN 1.5H:1V.
7. SURCHARGE SHOULD BE ADDED FOR ANY ROADS, FOUNDATIONS, MATERIAL STOCKPILES, ETC., NOT SHOWN ABOVE,
IN ACCORDANCE WITH FIGURE 4.
