A vertical retaining wall 8 m high is supporting a horizontal backfill having a moist unit weight of 17 kN/m3 and a saturated unit weight of 20kN/m3. Angle of internal friction above and below the water table are 30° and 25° respectively with OCR = 2 below the water table. Ground water table is located 3 m below the ground surface. Determine the at rest lateral earth force per meter length of the wall. Determine the location of the resultant force. Determine the at rest lateral earth force per meter length of the wall and location if it carries a surcharge of 100 KPa.
