| 摘 要： | 振动沉管灌注桩是建筑工程中常见桩选择之一，沉管桩随着土层较大变化易受到挤压而倾斜。沉管桩桩身缺陷可根据采得波形及结合实际情况分析。在无法确定其为何种缺陷时，可以采用开挖探查的方式，直接观察桩身的缺陷。同时可用高应变测试方法，得到基桩的极限承载力。

| Abstract: | As a familiar pile type used in civil engineering, the cast-in-place pile of vibro-diving casing can be easily squeezed, forming the defects in pile shaft. The defects in the pile shaft are analyzed based on the collected wave patterns and in combination with the practical engineering practice, when the defects are unable to be determined, the excavation method can be used to observe the defects in the pile shaft directly. Meanwhile, high strain testing method can be used to test the ultimate bearing capacity of the foundation piles. |
