Аннотация


Оценивается критическая нагрузка на изгиб частично заглубленной бетонной сваи в связном грунте с использованием численного B-сплайн метода и нелинейного коэффициента горизонтальной реакции вдоль сваи. На основе сравнения несущей способности свай по грунту и критической нагрузки на изгиб для исследования выбраны частично заглубленные сваи, для которых риск разрушения при изгибе более высок.

One of the failure factors of partially embedded piles under the structures is pile's buckling. In this research program buckling critical load of a partially embedded concrete pile in cohesive soil is evaluated by using B-spline numerical method and non-linear horizontal reaction coefficient along the pile. By comparing geotechnical load bearing capacity with buckling bearing one, partially embedded piles with higher risk of buckling failure than geotechnical one are chosen for investigation.
