Calculate and plot the active pressure distribution on the frictionless wall shown below. Also calculate the total thrust (active + hydrostatic force) and determine its point of application. In the figure given below:
Expert Answer
Given data, sand layer properties, 19 kN/m3 silt layer properties, 22 kN/m3 kPaH1 = 3m, H2 = 12m, Hwater = H1 = 3msurcharge, q = 111 kpaActive earth pressure coefficient (Ka);Types of earth pressure generated due to backfill are;(a) Active earth pressure(b) Earth pressure at rest(c) Passive earth pressureActive earth pressure: movement of the wall away from the backfill under the pressure caused by the backfill and surcharge. In active earth pressure, a little movement is required to mobilize.
