Aproximate solution of seismic bearing capacity of composite foundation under earthquake action

The ground slope face supposed Prantle's slope face. the computation of static earth pressure is enlarged seismic earth pressure. By employing pseudo-static approach and the method of limit equilibrium, the seismic bearing capacity of strip foundation on the composite foundation is derived. The computing methods of the seismic bearing capacity of the composite foundation on layering ground, rectangular foundation and circular foundation are discussed.The effect factors of seismic bearing capacity coefficients of the seismic bearing capacity are analysed. The basic is supplied for practical use in geotechnical engineering.
