摘　　要：笔者通过分析现行《规范》在桩基最终沉降量计算方面的四个制约因素和大量桩基沉降实测资料 ,确立桩土间的时空效应原理 ,确定桩基沉降由竖向变形和侧向变形两部分组成 ,压缩层厚度在桩尖平面以下 0 6 18B范围内 ,压缩层范围内土层的压缩模量Es=1 4 9E0 1～ 0 2 ,并建立起GanFour factors to influence the calculation of final settlement of pile foundation by using the current code are analyzed herein. Through the study on a large amount of field measuring data several results have been made, which deals with the principle of time\|space effects of the interaction between pile and soil, the settlements including vertical and lateral settlements, the thickness of compressive stratum being within 0 618B(B represents the width of the suporting platform) and E\-s=1\^49E 0\^1～0\^2 in the compressive stratum. Finally, a model (Gan\|Chen model) for the calculation of pile settlement has been suggested.
