桩周土阻力分布情况。
当地下条件较好时，人工挖孔桩通过合理的简化，可将其嵌岩灌注桩物理模型简化为端承桩，暂不考虑上部桩周土摩阻力。
If the geology condition is better, the physical model of man_dug pile can be regarded as end_bearing pile by reasonable simplification without considering the friction resistance of the soil.
打入式基桩施工引起的持续振动可引起桩周土液化，降低桩侧摩阻力，从而影响单桩承载力。
Owing to the liquefaction of soil around piles caused by sustained construction vibration the lateral resistance and bearing capacity of piles could be decreased.
