A number of load tests on timber piles embedded for their full length have indicated a safe load capacity of 40 tons. Load calculations are quite complex and lend themselves well to the use of a spreadsheet. At larger soil displacements, the proximity of slope adversely affected the lateral capacity of the soil-pile system and consequently the p-y curves. The ultimate load carrying capacity for each pile was also predicted using the static " -method, which is used by DOTD for pile design and analysis. In this analysis, we will assess the pile group using the same analytical methods that we previously used when analysing a single pile (NAVFAC DM 7.
