[摘要] 通過對剛性樁復合地基樁側阻力模型的假定，利用彈性力學的求解方法，推導不同側阻力模型下剛性樁復合地的樁土應力比公式，并與現場試驗數據對比，結果與實測數據吻合較好。由此表明在合適的邊界條件下，采用彈性力學方法求解剛性復合地基的樁土應力比，具有一定的工程實際意義。

Abstract: Assumed the side skin friction model, this paper derived the pile-soil stress ratio formula of rigid pile compostion foundation under different side skin frictions by adopting the elastic mechanical method,and comparesd theoretical results with test data. The result is in good agreement and shows using elastic mechanical method to calculate the pile-soil stress ration of rigid pile compositon foundation under adequate boundary conditions is practical.
