摘　　要：PHC桩沉桩实践与场地土室内压缩试验在现象上都存在土体体积的压缩,有一定的共性特征。文中利用场地土室内压缩试验e-p关系曲线变化特征,估计沉桩挤土的综合效应,从应力角度分析了某工程大量桩断施工原因,并提出处置办法。Both PHC pile driving practice and soil compression test exist the phenomenon of soil volume compression. The comprehensive effect of pile driving and soil squeezing was estimated based on the variation characteristics of e-P relation curve of soil compression test. The causes of a large number of pile breaks in a project are analyzed from the perspective of stress, and the disposal method is proposed.
