ВЛИЯНИЕ ТИПА АРМИРОВАНИЯ И ВЛАЖНОСТИ НА ПОВЕДЕНИЕ МАРГИНАЛЬНОГО ГРУНТА, УКРЕПЛЕННОГО ГЕОСИНТЕТИЧЕСКИМИ МАТЕРИАЛАМИ Effect of reinforcement type and soil moisture content on marginal soil-geosynthetic interactions

Аннотация


Проведено исследование так называемых маргинальных грунтов, которые экономически не являются пригодными для использования в сельском хозяйстве или при строительстве. Предлагается использовать такие грунты в качестве обратной засыпки, предварительно выполнив армирование геосинтетическими материалами (георешетка, нетканый геотекстиль, геокомпозиты, нетканый геотекстиль со слоем песка в 10 мм) для улучшения прочностных характеристик. Выполнены крупномасштабные лабораторные эксперименты на одноплоскостной срез, которые показали справедливость предположений об увеличении сдвиговых характеристик маргинального грунта, армированного различными геосинтетиками. Сделан вывод о том, что геосинтетический слой с высокой дренажной способностью может эффективно увеличить прочность маргинального грунта на сдвиг, при этом отмечается существенная зависимость результатов от влажности.
