- Discuss about the Carrying capacity of single pile in granular and cohesive soil ?arrow_forwardExplain the difference between a rigid analysis and a nonrigid analysis for lateral pile loading. Think about soil-structure interaction.arrow_forwardA concrete pile of size 50 cm x 50 cm is to be provided in a clay stratum whose unconfined compressive strength is 110 kPa. Compute the minimum length of pile required to carry safe working load of 450 kN with a factor of safety 2.5. Assume adhesion factor as 0.6.arrow_forward
- Explain these two questions based on pile foundations: i) How do the soil stress states and strain states change by the installation and structural loads? ii) Is the analysis of the load capacity of a pile is exact or is it an approximation?arrow_forwardWhat is the pile bearing capacity if the Downward drag = 0.6 psi, h1 = 30', h2 = 4', Frictional stress = 3.5psiAxial stress = 250psi.arrow_forwarda 15-meter precast concrete pile is to be lifted. if the unit weight of concrete is 23.54 kN/m3. And the section of the pile measures 400 mm by 400 mm.arrow_forward
- 3. Determine the allowable end bearing resistance of a 16" x 16" square pile bearing in a clay material 40 feet below the surface. The clay has a unit weight of 115 pcf and undrained shear strength of 2500 psf. Assume a factor of safety of 3.0 is required.arrow_forwardQ2/What are the Classification of Piles According to Method of Construction?arrow_forwardDescribe the factors of safety for design of piles.arrow_forward
- A large sign is to be supported on two steel poles, each of which will be supported by an 18 in diameter drilled shaft. The lateral wind load acting on the sign will be 3,000 lb and distributed evenly between the two piles. The centroid of this wind load will be 30 ft above the ground surface. The soils are sandy clays with su = 2,500 lb/ft2. Using a rigid analysis, compute the required depth of embedment and the maximum moment in each drilled shaft. Use a factor of safety of 3.0.arrow_forwardAn engineer is designing a deep foundation at a site underlain with loose to medium dense sandy silt and silty sand. Three pile types are being considered: driven prestressed concrete piles, PIFs, and drilled displacement piles. Discuss the advantages and disadvantages of each type.arrow_forwardA proposed highway bridge will be supported by 180 piles, each about 18 m long. The design load per pile is greater than 1000 kN. The soil conditions are neither unusually good, nor unusually bad, and you have limited experience with other pile foundations in the area. Based on this limited information, determine the number of pile load tests required for this project. State the main objectives of pile load tests.arrow_forward
