摘要
根据模型试验结果和对岩层中抗拔桩破坏模式的分析 ,通过研究已有的计算公式 ,提出了改进的计算岩层中抗拔桩承载力的公式和计算参数的确定方法 ,然后用模型试验的结果对计算公式进行了检验并用其预测了泸州长江二桥现场抗拔桩的极限抗拔承载力。
Based on the results of model tests and analysis of the failure modes of tension piles set into rock, the existing formulas for calculating the bearing capacity of tension piles are researched. An improved formula is put forward, and the relative parameters in the new formula are also proposed. Finally, the improved formula is validated by the results of the model tests and is used to predict the ultimate uplift bearing capacity of the in situ tension piles at the Second Luzhou Changjiang Bridge.
