Geotechnical Engineering-II [Lec #18: Terzaghi Bearing Capacity Equation]

  1. 1. 1 Geotechnical Engineering–II [CE-321] BSc Civil Engineering – 5th Semester by Dr. Muhammad Irfan Assistant Professor Civil Engg. Dept. – UET Lahore Email: mirfan1@msn.com Lecture Handouts: https://groups.google.com/d/forum/geotech-ii_2015session Lecture # 18 10-Nov-2017
  2. 2. 2 TERZAGHI’S BEARING CAPACITY THEORY Terzaghi (1943) developed the theory for continuous/strip foundations (simplest, 2D problem).  BNNDNcq qfcult '5.0''  Contribution of: Shear strength Surcharge Soil self- weight Nc, Nq and Nγ → Terzaghi’s Bearing Capacity Factors → Depend upon friction angle (Φ) of soil.
