Фронт поверхности скольжения, перемещаясь в нагружаемом грунтовом теле, тормозится на деформационных неоднородностях. Преодоление упругого сопротивления на них происходит со скачком перемещения. Перемещения на группе деформационных неоднородностей кооперативно проявляются в виде скачка осадки пробы грунта при компрессионном сжатии. Деформационные неоднородности представлены, в рамках 2-х компонентной модели деформации, наиболее крупными жёсткими включениями в матрице глинистых частиц и микроагрегатов. Показаны схематично связь перемещения поверхности скольжения с деформациями сжатия пробы, механизм скачкообразности осадки и цикличности скорости осадки. Эффект скачкообразности осадки проявляется как при нагружении пробы, так и при ползучести. Преодоление вязкого трения в глинистой матрице и упругого сопротивления на деформационных неоднородностях вызывает отклонение физической поверхности скольжения от поверхности максимальных касательных напряжений, что создаёт эффект внутреннего трения.</p></abstract><trans-abstract xml:lang="en"><p>Deformations of a clay soil sample are a consequence of shearing along sliding surfaces. The sliding surface front, moving in the loaded soil body, is slowed down by deformation heterogeneities. Overcoming the elastic resistance on them occurs with a displacement jump. Displacements on a group of deformation heterogeneities cooperatively manifest themselves in the form of a jump in the soil sample's settlement under compression. Deformational heterogeneities are represented, within the framework of a 2-component deformation model, by the largest rigid inclusions in the matrix of clay particles and microaggregates. The schematic diagram shows the relationship between the displacement of the sliding surface and the compression deformations of the sample, as well as the mechanism of stepwise settlement and the cyclicity of the settlement rate. The effect of stepwise settlement is observed both during the loading of the sample and during creep. Overcoming viscous friction in the clay matrix and elastic resistance on deformation heterogeneities causes the physical sliding surface to deviate from the surface of maximum tangential stresses, which creates the effect of internal friction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>деформационная неоднородность</kwd><kwd>деформация</kwd><kwd>напряжение</kwd><kwd>поверхность скольжения</kwd><kwd>микроагрегат</kwd><kwd>скорость деформации</kwd><kwd>ползучесть</kwd><kwd>скачок скорости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deformation heterogeneities</kwd><kwd>deformation</kwd><kwd>stress</kwd><kwd>sliding surface</kwd><kwd>microaggregate</kwd><kwd>settlement rate</kwd><kwd>creep</kwd><kwd>velocity jump</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Цытович Н.А., Зарецкий Ю.К., Малышев М.В. и др.
