Аннотация


Закономерности ползучести слабого глинистого грунта с органическими включениями из района Гуанчжоу (Китай) исследовались с использованием лабораторного прибора прямого сдвига. К образцам прикладывалось нормальное напряжение, соответствующее смещение контролировалось при постоянном горизонтальном напряжении сдвига. В зависимости от уровня сдвиговых напряжений наблюдались все три стадии ползучести, для описания которых предложена единая нелинейная модель вязкоупругопластического типа с 13 независимыми постоянными параметрами. Отмечается хорошее совпадение с экспериментом и возможность использования предложенной модели для прогноза оползневых явлений.
