EXAMPLE 10.1. CALCULATION FOR ALLOWABLE CAPACITIES OF WOOD PILES
(concluded)
Solution for #1: Find the allowable tension and compression capacity of the wood pile embedded in
soil as follows:
• To determine the resultant pressure from the soil on the pile:
• Geometrical properties of the pile surfaces upon which pressure from the soil is applied to the
pile are:
Allowable compression capacity:
Allowable tension capacity:
The purpose of Table 10-7 is to illustrate the effects of varying diameters, depths of embedment, and
installation methods on allowable capacities. See Section 10.5.4 for information of installation methods.
Example calculations used to determine the values in Table 10-7 are used in Example 10.1. The values in
Table 10-7 are not intended to be used for design purposes.
