Установлено, что зависимость пластической деформации дискретных материалов, в том числе обработанных вяжущим, от числа приложенных повторных нагрузок описывается логарифмической или степенной функцией. Анализ экспериментальных данных показал, что параметры логарифмических и степенных моделей зависят от величины главных напряжений, при которых были выполнены трехосные испытания, а также от показателей физических свойств материалов. В статье приведены результаты экспериментальных исследований пластического деформирования щебеночно-песчаной смеси из гранита, известняка и песчаника, а также песка, укрепленного битумом. Приведена методика вычисления параметров логарифмических и степенных математических моделей и определены параметры для этих материалов
