Комплексный расчет буронабивных свай на участке строительства системы скоростного легкорельсового транспорта в Астане, Казахстан

Введение. Легкорельсовый транспорт (ЛРТ) — система общественного транспорта, строительство которого ведется в г. Астане в настоящее время. Рассматривается проект ЛРТ на сложных грунтах Астаны. Из-за проблемных грунтов в обоих крупных проектах использовались свайные фундаменты.

Материалы и методы. Фундамент моста был построен с использованием буронабивных свай длиной от 8 до 55 м и диаметром сечения от 1,0 до 1,5 м. Каждая буронабивная свая имеет расчетную несущую способность от 4500 до 9500 кН.

Результаты. Представлены результаты испытаний буронабивных свай на сплошность (стандарт Американского общества испытания материалов D6760–08) и статическую нагрузку (ГОСТ 5686–94). В этих условиях обеспечение сплошности бетонной части каждой буронабивной сваи имеет решающее значение. Для проверки сплошности следует использовать метод межскважинного акустического каротажа. Сегодня наиболее надежным методом оценки сплошности глубокого свайного фундамента на строительной площадке является метод межскважинного акустического каротажа, представляющий собой метод неразрушающего контроля. После установки обследование сплошности часто служит лучшим практическим способом оценки состояния ствола.

Выводы. Проанализированные результаты получены на реальном объекте. Приведены предложения по проведению испытаний в условиях сложных грунтов Казахстана.
