Уважаемые коллеги!
12 августа (среда) 2026 г. в 10:00 в конференц-зале ИНГГ СО РАН (к. 315) состоится геофизический семинар:
"Алгоритм моделирования сейсмических волновых полей с использованием сеточного метода и нейронной сети".
Научный доклад по материалам диссертации на соискание учёной степени кандидата наук.
Докладчик: Гондюл Елена Александровна, младший научный сотрудник лаборатории численного моделирования многофизичных процессов, Институт математики им С. Л. Соболева СО РАН
Научный руководитель: Лисица Вадим Викторович – доктор физико-математических наук, заведующий лабораторией численного моделирования многофизичных процессов, Институт математики им. С. Л. Соболева СО РАН
Аннотация: В докладе будет представлен разработанный метод расчёта волновых сейсмических полей на основе комбинирования сеточных методов решения системы уравнений динамической теории упругости с методами машинного обучения для повышения эффективности и ускорения моделирования данных сейсмических наблюдений. Используется нейронная сеть NDM-net (Numerical dispersion mitigation neural network) для подавления численных ошибок в сейсмических данных, отвечающих двумерным и псевдо-трёхмерным моделям изотропной упругой среды. Разработана методика выбора оптимального набора положений источников для формирования обучающей выборки. Рассматривается применение разработанного алгоритма для сейсмического мониторинга захоронения CO2. При использовании NDM-net подавляется как численная дисперсия, так и численные ошибки при возмущении скоростной модели среды. При этом вычислительное время уменьшается до 6 раз в двумерном случае и до 12 раз в трёхмерном.
