摘要
考虑桩侧摩阻力随深度线性增加，在此基础上推导了沉桩挤土效应的空间解析解，该解析解能预测沉桩时桩周土体的竖向位移；离心模型试验值、有限元计算值与解析解值作了比较分析，解析解值能较好的反映试验值，土体竖向位移解析解值与有限元计算值接近。
Spatial analytical formulas are derived with the consideration that the pile shaft friction increases linearly with depth, the analytical formulas can forecast vertical displacement of soil surrounding the pile. Analytical solution are compared with data measured from centrifugal model test and solution calculated with finite element method, which shows that analytical solution can reflect correctly to some degree what gained from test and is very close to that calculated with finite element method.
