A bridge construction site requires load testing of piles on site to check if the pile can take the maximum load. From the past experience it is known that there is 10% chance that a pile will fail under the maximum load. Assuming the pile tests are independent events and 10 piles are tested, what is the probability that: (a) exactly 3 piles will fail? (b) less than 3 piles will fail?

Piles are needed to support columns in a high rise building at a particular site. The probability of failure of a pile due to excessive axial load is estimated to be 10 Suppose that four soch piles are required under each colunas and there are 20 identical columns in the filding Assume that the failure of piles are statistically independent of mach other. (a) What is the probability that none of the piles under a column foundation will fail (b) What is the probability that none of the columns in a building will staffer damage due to p pile failure?
In the selection of the ram of a pile driver, it is desired that the ram lose all of its kinetic energy at each blow. Hence, the velocity of the ram is zero immediately after impact. The mass of each pile to be driven is 275 kg, and experience has shown that a coefficient of restitution of 0.38 can be expected. What should be the mass m of the ram? Compute the velocity v of the pile immediately after impact if the ram is dropped from a height of 4.5 m onto the pile. Also compute the energy loss AE due to impact at each blow. 4.5 m 2.6 m Answers: m = i kg V = i m/s ΔΕ- i J
A reinforced concrete circular pile is driven to the soil as shown below. Calculate the negative skin friction force acting on the pile.
Sand falls into a conical pile at the rate of 10 cu. ft. per min. The radius of the base of the pile is always equal to one-half of its height. How fast is the height of the pile increasing?
Sometimes pile driving contractors use predrilling when installing piles. This method consists of drilling a vertical hole that has a smaller diameter than the pile, then driving the pile into this hole. Could predrilling affect the side friction resistance? Why? Is the diameter of the predrill hole important? Why?
Describe the relationship between the capacity of a tested or analyzed pile and the driving record.
What is the significant role of setup and relaxation on driven pile capacity?
A 250 mm square, 15mm long prestressed concrete pile (fc = 40 mpa) was driven at a site in Amsterdam as described by Heijnen and Janse. A conventional load test conducted 31 days later produced the load -settlement curve shown in figure. Using Davisson's method, compute the ultimate load capacity of this pile
A static load test has been conducted on a 60 ft long, 16-in 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, settlement at head = 1.211 in, settlement of telltale rod A=1.166 in, settlement of telltale rod B=1.141 in. Find: (1) Use the data from telltale rod A to compute the modulus of elasticity of the pile, then (2) use this E value and the remaining data to compute qn' and the average fn value.
A pile group with a design load of 200 tons is to be used to support the individual column footings in a modern building. However, it is known that the load may on rare occasions reach as high as 300 tons. Civil engineering consultants have used previous experience with similar pile foundations, supplemented with soil tests, to generate an estimate of 0.75 for the probability of a pile group being able to support the 300-ton load. They have calculated, further, that of the 25% of the piles that will not support the 300-ton load, 50% will fail under a load of 270 tons or less, while 70% will fail under a load of 285 tons or less. However, the safety case for the building requires that the probability be greater than 0.9 that a pile group can carry the extreme load of 300 tons. The civil engineer in charge may order just one proof test, which may be at either 270 or 285 tons. He would prefer the test with the lower load, as it is less difficult and cheaper to administer. Suppose that you…
A static load test has been conducted on a 60 ft long, 16 in 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, settlement 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 telltale rod A to compute the modulus of elasticity of the pile, then use this value and the remaining data to compute q'n and the average fn value. Hint: Telltale rod A is anchored only 1 ft from the mud line (the top of the soil). There is essentially 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.
