نویسندگان

چکیده

Abstract Seismic bearing capacity of strip footings in cohesive soil slopes considering various embedded depths is investigated this study. Novel solutions using pseudo-static method and finite element limit analysis (FELA) with upper bound (LB) lower theorems are presented. The influences footing depth, slope angle, height, undrained shear strength acceleration on failure mechanisms examined dimensionless parameters. With the comprehensive numerical results, multivariate adaptive regression splines (MARS) model then utilized to simulate sensitivity all input parameters (i.e., normalized depth D/B, height H/B , distance from top edge L/B angle β ratio c u /γB factor, k h ). degree influence each design parameter produced, an empirical equation for output factor N ) proposed. study results accessible charts, tables, practitioners.

Seismic Bearing Capacity of Strip Footings on Pile-Stabilized Slopes

This paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. The resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. This comparison indicates an acceptable agreement. The variants of the study incl...

Bearing Capacity of Strip Footings near Slopes Using Lower Bound Limit Analysis

Stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. The complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. The curr...
