Say, there are four layers below a square footing. Up to the depth of footing the soil is clay. First layer: clay soil, thickness H1, coefficient of consolidation: Cv1 Second layer: clay soil, thickness H2, coefficient of consolidation: Cv2 Third layer: sandy soil Fourth layer: clay soil, thickness H4, coefficient of consolidation: Cv4 The fourth layer is followed by impermeable rock. How would you apply Terzaghi's classical formula , t = Tv/Cv*hd^2 to this problem? (hd = drainage path) To be more specific, how can we calculate time required for 50% consolidation of entire soil system? What will be the values of Cv and hd for the first layer?
Your videos are really good! I enjoy your minimalist approach. Congratulations and thank you for sharing them!
you are amazing teacher :) 👨🏫
Thank you! 😃
