Cantilever Sheet Pile Design Get link Facebook X Pinterest Email Other Apps By Erisyoga - November 21, 2012 Design of Cantilever Sheet Pile Wall Penetrating Sand DESIGN OF CANTILEVER TYPE SHEET PILE PENETRATING SAND Enter the value of the angle of shearing resistance of sand (f) degrees Enter the value of the dry unit weight of sand (gd) kN/m3 Enter the value of the saturated unit weight of sand (gsat) kN/m3 Enter the sheet pile depth to sea level (L1) m Enter the sheet pile depth from sea level to dredge line (L2) m the value of the effective unit weight of sand gsub = gsat - (gw = 9.81 kN/m3) = kN/m3 coefficient of active earth pressure (Ka) = (1 - sin f) / (1 + sin f) = coefficient of passive earth pressure (Kp) = (1 + sin f) / (1 - sin f) = pressure P1 = gd L1 Ka = kPa pressure P2 = (gd L1 + gsub L2) Ka = kPa distance L3 = P2 / [gsub (Kp - Ka)] = m force F1 = P1 L1 / 2 = kN/m force F2 = P1 L2 = kN/m force F3 = (P2 - P1) L2 / 2 = kN/m force F4 = P2 L3 / 2 = kN/m force F = F1 + F2 + F3 + F4 = kN/m distance d = [F1 (L1 / 3 + L2 + L3) + F2 (L2 / 2 + L3) + F3 (L2 / 3 + L3) + F4 (2 L3 / 3)] / F = m pressure P5 = (gd L1 + gsub L2) Kp + gsub L3 (Kp - Ka) = kPa coefficient A1 = P5 / [gsub (Kp - Ka)] = coefficient A2 = 8 F / [gsub (Kp - Ka)] = coefficient A3 = 6 F [2 d gsub (Kp - Ka) + P5] / [(gsub)2 (Kp - Ka)2] = coefficient A4 = F (6 d P5 + 4 F) / [(gsub)2 (Kp - Ka)2] = To find the length L4, the following equation must satisfy (L4)4 + A1 (L4)3 - A2 (L4)2 - A3 L4 - A4 = 0 Enter a trial value for the length L4 m the right hand side (RHS) of the above L4 equation , if different from zero, assume a new trial value for L4, enter in the box in the previous step and calculate RHS again. Repeat these steps until RHS matches zero. the theoretical depth of sheet pile D = L3 + L4 = m the actual depth of sheet pile Dact = 1.3 D = m the total height of sheet pile L1 + L2 + Dact = m Calculation of maximum moment and section modulus distance of plane of zero shear Z' = [2 F / gsub (Kp - Ka)]1/2 = m maximum moment Mmax = F (d + Z') - [gsub (Kp - Ka) / 6] (Z')3 = kN.m SteelType Allowable Stress(sall) MN/m2 ASTM A-328 170 ASTM A-572 210 ASTM A-690 210 Enter, from Table above, the allowable flexural stress of the sheet pile material sall = MN/m2 section modulus of sheet pile S = Mmax / sall = m3/m of wall Summary of Design Angle of shearing resistance of sand (f) degrees Dry unit weight of sand (gd) kN/m3 Saturated unit weight of sand (gsat) kN/m3 Depth to sea level (L1) m Depth from sea level to dredge line (L2) m Theoretical depth of sheet pile D = m Actual depth of sheet pile Dact = m Total height of sheet pile L1 + L2 + Dact = m Maximum moment Mmax = kN.m Allowable flexural stress of the sheet pile material sall = MN/m2 Section modulus of sheet pile S = m3/m of wall Copyright 2007-2012 A.
