Объект исследования - применение методов испытаний на ударную вязкость при малых деформациях для контроля качества сращиваемых забивных свай. Распространенное мнение о невозможности использования метода исследования составных забивных свай опровергается результатами, полученными на практике, и требует уточнения. Метод. Перечислены методы, используемые для компенсации ограничений стандартных методов испытаний на низкую деформацию при исследовании сложных свайных конструкций. Приведены сведения об основных конструктивных особенностях свайных забивных свай. Полученные результаты. Предложены модели акустического отклика различных типов стыков композитных свай. Выделены особенности использования испытаний на низкую деформацию на конструкциях этого типа. Приведены примеры обследования композитных свай со стыками различных типов из полевой практики ООО «АИГЕОС» (Москва, Россия) и ООО «ОЗИС-Венчур» (Санкт-Петербург, Россия).
