A static load test has been conducted on a 60-ft long, 16-inch square reinforced concrete pile which has been driven from a barge through 20 ft of water, then 31 ft into the underlying soil. Telltale rods A and B have been embedded at points 30 ft and 59 ft from the top of the pile, respectively. The data recorded at failure was as follows: Load at head = 139,220 lb, settle- ment at head = 1.211 in, settlement of telltale rod A = 1.166 in, settlement of telltale rod B= 1.141 in. Use the data from tell tale rod A to compute the modulus of elasticity of the pile, this value and the remaining data to compute q' and the averagef, value in the soil. , Telltale rod A is anchored only 1 ft from the mud line (the top of the soil). There is es- ially no side-friction resistance between the top of the pile and this point, so the force at a depth of 30 ft is essentially the same as that at the top of the pile.
