ОПТИМИЗИРОВАННЫЙ ЧИСЛЕННЫЙ МЕТОД РАСЧЕТА УПЛОТНЕНИЯ НЕНАСЫЩЕННОГО ГРУНТА ПРИ НАГРУЗКЕ, ЗАВИСЯЩЕЙ ОТ ВРЕМЕНИ An optimized numerical validation for unsaturated soil consolidation under time-dependent loading

Qian He, Quan Yuan, Lin Lang

Аннотация


Предложен метод неявных разностей (HPI) для повышения точности и скорости вычислений при расчете уплотнения неводонасыщенного грунта. Стабильность предложенного численного решения проверена с помощью критерия фон Неймана. Пример, рассматривающий постоянную во времени загрузку, демонстрирует надежность решения методом HPI. Расчеты для нагрузки, зависящей от времени, подтверждают, что схема HPI значительно превосходит метод явных разностей (EDM). Решение HPI может быть использовано для исследования уплотнения неводонасыщенного грунта при переменных нагрузках, в том числе экспоненциальных и синусоидальных.
