The greatly reduced capacity of a single pile resulting from the negative friction leaves the end-bearingpile unsuitable in the backfilling soil.
实例分析表明,由于桩侧负摩阻力的影响,单桩承载力大为降低。产生负摩阻力的土层,不宜采用端承型桩基。

Testing bearingpile with low strain method will be some defects in the bottom if the echo from the tip has the same phase as the pulse at the top.
用低应变法检测嵌岩桩,若桩底出现明显同相反射,多数因桩底缺陷引起。

Then, the effect of model parameters on displacement of soil and inner stress and displacement of bearingpile were discussed and rule of pit deformation was studied too.
