Take the direction of wall movement as the arrow shows. Plot the pressure diagram , and show the resultant force and its point of application and direction . Use the Rankin e analysis and ignore the soil on the front side. 2. Calculate the force due to the passive earth pressure against the front side of the wall shown at right. Plot the pressure diagram , and show the resultant force and its point of application and direction . Use the Rankin e analysis and ignore the soil on the back side. 3. How would the resultant force change in problem 2 if water became ponded half way up the back side of the wall? 4. A gravity wall retains backfill inclined at an angle of 25°.
