Year: 2025
Type: article
Abstract: In engineering practice, many foundations are forced to be placed on slopes, whose stability is deeply affected by seismic force. Therefore, an accurate assessment of the seismic bearing capacity of strip foundations close to slopes is a crucial guide for engineering. Herein, an analytical procedure considering pseudo-dynamic influence is proposed, which offers a new assessment framework for seismic bearing capacity of strip foundations close to slopes on non-uniform soils. Considering the temporal and spatial characteristics of earthquake action, the seismic bearing capacity of foundations at different normalized frequencies is obtained, and depth profiles of seismic acceleration coefficients at different normalized frequencies are presented. The consistency between this paper’s computational results and the published literature substantiates the dependability of the proposed analytical procedure. The sensitivity analyses are carried out for horizontal seismic coefficients, normalized frequencies, damping ratios, internal friction angles, slope angles, cohesion, and non-uniform coefficients, and the results are presented for practice reference in engineering.
