滑动测微计在自平衡条件下的桩身内力测试

摘要

在自平衡桩基静载荷试验的基础上，采用滑动测微计法作为内力测试手段进行桩身内力测试，得到了自平衡条件下的桩身轴力和桩侧摩阻力测试曲线，并对测试结果进行了对比与分析，提出了需要进一步研究的方向。%Based on the static loading test of the self-equilibium pile foundation,the paper adopts the sliding micrometer method to undertake the pile internal stress test as the internal stress measurement,concludes the pile axial stress and friction test curve along piles,undertakes the com-parison and analysis of the test results,and points out further orientation of the research.
