摘要
通过在人工挖孔嵌岩桩桩顶、桩端及桩周各主要土层的分界面埋设钢筋计的静荷载试验,分析了嵌岩桩侧阻力、端阻力的变化规律。并对实测结果与勘察报告建议值以及规范计算值进行了比较,探讨了岩性、嵌岩深度等对承载力的影响,提出了计算嵌岩桩承载力所需系数的取值。
Based on the static loading tests on rock socketed piles in which the stain gauges were mounted at the top and the interfaces of soil strata, the behaviors of skin resistance and toe resistance are analyzed. The results of the test, the values suggested in the investigation report and calculating values are compared and the effects of rocky character, depth of rock socketed are discussed. The coefficients for calculating the bearing capacity of rock socketed piles are presented.
