摘要
通过对深厚软土地基中超长桩静载荷试验和桩身轴力实测资料的分析 ,研究了软土中持力层为粘土、卵石层的超长桩的承载特性和荷载传递机理 ,得到了桩端阻力、桩侧摩阻力发挥规律和桩身压缩变形规律 ,为今后超长桩的理论研究和设计应用提供了重要的参考作用。
Based on the data analysis of static load test and axial force of piles in deep soft soil foundation, the bearing capacity behavior and load transfer mechanism of super-long piles in clay and pebblebearing stratums have been analyzed.The action laws of pile end resistance and lateral friction resistance and shaft compression are obtained.And some important references for the theoretical research and technical application of super-long piles are provided.
