МОДЕЛЬ ВЕРОЯТНОСТНОГО АНАЛИЗА НЕСУЩЕЙ СПОСОБНОСТИ СВАИ НА ОСНОВЕ ЭКСТРАПОЛЯЦИИ КРИВЫХ НАГРУЖЕНИЯ Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves

Аннотация


экстраполяции кривых нагружения, полученных в результате испытания статической наг$ рузкой, рациональной функцией. В предварительном анализе экстраполяция основывалась на применении ряда математических функций, которые постепенно исключались путем итеративно$ го отбора и фильтрации. Используя рациональную функцию для экстраполяции кривой нагрузка− осадка, получена четко идентифицируемая часть, в которой асимптота вертикальна, указывая на достигнутое предельное состояние грунта и/или сваи. Вероятностный анализ показал, что одноз$ начного значения несущей способности сваи получено не было, а спектр значений зависит от ве$ роятности наступления соответствующего события.
