摘要
在单桩竖向静载荷试验中 ,对 Q— s曲线曲率变化不规则、沉降过程异常及桩顶总沉降量较邻近桩明显偏大、回弹率较邻近桩明显偏小的桩 ,应复查其桩身完整性。若确认为其桩身断裂 (指桩身开裂、缩颈、夹泥、蜂窝、离析、混凝土低强度区等缺陷贯穿截面 ) 。
After static test,t he pile integrity should be re-tested if Q—s curve is found to be irregular,or sinking obviously greater than nearly pi les,or resilience obviously smaller than nearly piles.If the pile is found to be broken,which means defects such as crac k,construction,obstruction,honey-comb,vo id of paste,change of concrete quality a re through the section,the bearing capac ity should not be gave according to the available code.
