| 摘 要： | 静力试桩中桩身轴向应变是分析荷载传递机理的基础。滑动测微计可连续地测定桩身每米内的平均应变,通过荷载-应变关系曲线可较准确地计算轴向力、摩阻力、端阻力、负摩阻力;水平试桩时安装二条测管可准确地推算挠度曲线、最大弯矩点,临界荷载、极限荷载等桩基设计的主要参数,还可全面地评价桩身质量。该仪器不仅可用于各类试桩,还可用于各类岩土工程的现场位移监测。

| Abstract: | The complete distribution of strains along a pile is the basic for studying the load transfer motion in static pile test. Sliding Micrometer developed at Switzerland can measure the complete distribution of average strains with 1m gauge length along the pile continuously.It is easy to calculate the main parameters used in pile design such as the positive and negative skin friction,point resistance force using the load strain relation curve and also the deflection curve,maximal bending point, critical load a... |
