Numerical Analysis for Undrained Bearing Capacity of Eccentrically Loaded Footings near Slopes

摘要

Estimating bearing capacity of foundations is one of the key issues ingeotechnical practices. Footings have to be built on slopes or near thecrest of slopes in some civil engineering practices. This studyinvestigated the combined bearing capacity behavior of strip footingsnear undrained soil slopes under VM loading conditions, as well asvertical bearing capacity, using the finite element analysis method.Factors, such as soil properties, slope angle, slope height, footinglocation from crest of slope, which affect the bearing capacity behaviorof foundations, are analyzed through parameters studies. Failure loadenvelopes in VM load space for some cases are presented andsuggestion is made for future studies of this problem.
