Lateral Earth Pressure
Static Ka, Kp and Ko: Calculating the active, passive and at-rest lateral earth pressure coefficients based on both Rankin and Coulomb methods. The latter considers the effect of soil-wall friction, backslope, and wall batter angle. The magnitude of the resultant force and its point of application is also calculated.
Seismic Kae and Kpe: Lateral earth pressure coefficients for earthquake condition are calculated according to Mononobe-Okabe method for different horizontal and vertical components of the ground acceleration. Detailed values of Kae and Kpe are calculated for every 0.05g steps of vertical and horizontal ground accelerations. In addition to earth pressure coefficients, the seismic surcharge load (Pae – Pa) and total seismic force (Pae) behind the retaining wall are presented.
