桩筒复合基础筒体结构优化及承载性能分析
Optimum structural design and loading advantage analysis of pile-bucket foundation
摘要
Abstract
To prevent structural damages , a pile-bucket foundation has an inherent frequency which should be sepa-rated from the natural frequency when designing its size.In this paper, the optimal aspect ratio and height of the skirt of a pile-bucket foundation are determined based on modal analysis through ABAQUS software.A comparison is made between the pile-bucket foundation and traditional a single pile foundation to explore the difference in their bearing performances.To verify the reliability of the numerical model , indoor model tests were carried out.The re-sults show that the bearing capacity and sour resistant effect of the pile -bucket are better than those of the single pile foundation, and increasing the diameter of the cylinder is an important factor to increase the bearing capacity ; how-ever, when the height of the cylinder exceeds a certain value , the bearing capacity will not increase significantly.关键词
