DIRECTION: Solve the following problems. Show your solution clearly in the blank sheet provided along with this questionnaire. Every computation must be round off to two decimal places. Box your final answer and avoid any erasures. PROBLEM NO. 1 (50 POINTS): The soil profile and soil properties at a site are shown in the table below. A group of 20 concrete piles in a 4 x 5 matrix and of length 10.5 m is used to support a load. The pile diameter is 0.50 m spaced at 1 m. Determine the allowable load capacity for a factor of safety of 3. Calculate the total settlement (elastic and consolidation) under the allowable load. Assume Ep=20 X 106 kPa. Type of Deposit Sand Depth (m) 0.00-15.00 3 (location of GWT) 15.00 - 17.00 > 17.00 Soil Test Result y = 16.9 kN/mº. Vsat = 17.6 kN/m3 cs = 270, Eso = 20 MN/m2 my = 3.5 x 10-4 m²/kPa = = Soft Clay Rock PROBLEM NO. 2 (50 POINTS): Given the following data: . . . . • H1 = 3.4 +0.1(last digit ID number) m H = 7 + 0.1(last digit ID number) m Soil Unit Weight at first layer = 16.5 +0.1(last digit ID number) kN/m3 Soil Unit Weight at second layer (Saturated) = 18.7 + 0.1(last digit ID number) kN/m3 01 = 31+ last digit ID number 02 = 35 + last digit ID number q = 16+ 0.2(last digit ID number) kN/m2 . . . Determine the following: a. Lateral Earth Force at Rest b. Active Earth Pressure (Rankine and Coulomb) C. Passive Earth Pressure (Rankine and Coulomb)
