摘要
通过在砂土地基中使地下水位下降引发地基土沉降条件下的3×3竖直群桩复合地基模型试验,研究了地基土沉降对在役复合地基基础沉降、桩土应力比和桩身轴力的影响规律。试验结果表明:随着地基土沉降的增加,基础的沉降加大,桩-土应力比提高,桩身轴力有所增大。
Model experiment on 3×3 group piles composite foundation in sand foundation with ground subsidence caused by the groundwater level lowering was conducted.The influence of ground subsidence on the settlement,pile-soil stress ratio and axial force of piles of existing composite foundation were studied.Results show that settlement,pile-soil stress ratio and axial forces of piles increase gradually along with the increasing of ground subsidence.
