Definition of Limiting Pressure Upon Protections in View of Seismic Influences

Abstract

The design procedure of active and passive pressure of a ground on retaining walls is resulted in view of seismic influences. The power influence arising at earthquakes is expressed in the mass seismic forces having the inertial nature and determined depending on seismic acceleration. The decision of a problem on limiting pressure upon protecting walls is executed with application of a hypothesis about rectilinear lines of sliding. For this purpose settlement Kuhlman circuit is used. Formulas for calculation of limiting pressure upon a retaining wall are received by the direct decision of Kuhlman circuit. Thus the direction of seismic force is accepted horizontal. Influence of seismic force for different intensity of earthquakes on size of active and passive pressure of a ground is shown. Expressions for factors of active and passive pressure of a ground on retaining walls are offered to be used in practical calculations for seismic areas.
