Seismic lateral earth pressure coefficients for c? soils by slip line method
In this paper, the author proposes a rotation of axes in the solution of slip line equations for determination of lateral earth pressure with the presence of seismic loading under general conditions. A general c? soil system under a general condition can be considered so that Kp?, Kpc, Kpq, Ka?, Kac and Kaq can all be determined. For passive pressure, Kpc is found to be much greater than Kp? and the effect of seismic coefficient on passive pressure is relatively small as compared with the corresponding situation for active pressure. The use of iterative analysis is found to be useful for passive pressure determination but unimportant for active pressure determination.
