Steel Sheet Piling Design Manual
The design of sheet pile retaining walls requires several successive operations: (a) evaluation of the forces and lateral pressures that act on the wall, (b) determination of the required depth of piling penetration, (c) computation of the maximum bending moments in the piling, (d) computation of the stresses in the wall and selection of the appropriate piling section and (e) the design of the waling and anchorage system. Before these operations can be initiated, however, certain preliminary information must be obtained. In particular, the controlling dimensions must be set. These include the elevation of the top of the wall, the elevation of the ground surface in front of the wall (commonly called the dredge line), the maximum water level, the mean tide level or normal pool elevation and the low water level. A topographical survey of the area is also helpful.
