摘要

随着中国经济的快速发展,公路桥梁的规模和数量迅速增加,超长桥梁越来越多。超大型、超深地基数量不断增加,采用施工方便、承载力高的钻孔灌注桩。由于桩的受力机理受成桩工艺、土体特性、桩材料特性、桩几何特性、荷载等诸多因素的影响,在桩基础工程实践中广泛应用的竖向荷载作用下单桩的应力传递机理尚未完全了解。超长桩的影响因素比较复杂,其受力机理和承载变形特征还比较模糊,目前还没有较好的计算理论和方法,能够准确定量地分析超长桩基的应力应变,模拟整个变形过程。本文采用大型有限元软件ANSYS对超长钻孔灌注桩在竖向荷载作用下的桩土接触损伤进行了模拟分析,掌握了超长钻孔灌注桩的竖向承载力。

Research on Vertical Bearing Capacity of Super-Long Bored Pile
With the rapid development of China’s economy, the scale and quantity of highway bridges are increasing rapidly, and there are more and more extra-long bridges. The number of super-large and ultra-deep foundations is increasing, and bored piles with convenient construction and high bearing capacity are adopted. Because the stress mechanism of pile is influenced by many factors, such as pile forming technology, soil characteristics, pile material properties, pile geometric characteristics, load, etc., the mechanism of stress transfer from single pile under vertical load, which is widely used in pile foundation engineering practice, has not yet been fully understood. The factors affecting the super-long pile are more complicated, its stress mechanism and bearing deformation characteristics are still rather vague, so there is no better calculation theory and method, which can accurately and quantitatively analyze the stress and strain of super-long pile foundation and simulate the whole deformation process. In this paper, the simulation analysis of pile-soil contact damage of super-long bored pile under vertical load was carried out by large-scale finite element software ANSYS, and mastered the vertical bearing capacity of super-long bored pile.
