TABLE OF CONTENTS The actual design of a shoring wall is usually done with the use of computer software developed to specifically perform the calculations. These calculations are particularly suited to solution by computer as they tend to be iterative in nature. It is, however, important to understand the basis of the calculations so that checks can be made to assure that computer solutions are credible.
This chapter will not provide actual design examples. Many examples are detailed in Chapter 17 as well as the reference texts outlined in the Bibliography. This chapter will, however, detail design methods which might be followed to design the various components of a shoring system.
By continuous wall, we mean a wall in which the section is continuous throughout, such as a sheet pile wall, slurry wall, or secant wall with intermediate piling at the same depth as the primary piles (see Figure 3.38). The design of such a wall might be performed in the following manner:
Step 1. Define parameters of wall and soil
Height of wall: H
Soil parameters: c, ?
Surcharge: UDL, Boussinesq
Unit weight of soil: ?
Water table on either side of wall
Step 2. Develop K a, K p, q
Step 3. Select a pressure diagram (see Figure 11.1). Develop the pressure diagram based on a unit length of wall (1 foot length).
