摘要
通过对某工程的冲孔灌注桩(试桩)进行静载试验、钻芯法检测和高应变法检测,分析了该桩承载力严重不足的主要原因,是桩侧泥皮太厚而造成其摩阻力降低。同时指出各种桩基检测方法在分析其质量问题时均有一定的局限性,应同时采用两种或两种以上的方法。
Static loading test, core drilling method and high strain dynamic testing on an punching cast-in-place pile was taken in a project. The reason that the bearing capacity of the pile is far below than design, is there is too thick mud at the side of the pile that decrease frictional resistance of pile. According to the shortages of just use one test method to check quality problem, use two or more kinds tests while checking quality problem is advised.
