Характеристики конструкций моста в поврежденном состоянии изучены недостаточно, поэтому существует высокий риск их непредсказуемого поведения, что может привести к сбоям в работе, которые станут причиной серьезных аварий и техногенных катастроф. Масштабы такой опасности значительно возрастают в условиях экстремального климата Сибири и Севера. Повреждения и разрушения сооружений подтверждаются многими фактами.</p><p>Цель работы состоит в экспериментальном моделировании несущей способности моста после полученного повреждения, изучении состояния конструкций моста в различных условиях и определении мер по его восстановлению.</p></sec><sec><title>Методы</title><p>Методы.
