粉质黏土中桩承载力试验研究

Experimental study of the pile bearing behavior in the silty clay

通过桩静载荷试验对粉质黏土中桩的承载性能进行了试验研究,试验结果显示,粉质黏土中桩的侧摩阻力系数为37.6 kPa,桩的端摩阻力系数可达3.34 MPa,位于粉质黏土层中的桩端阻力占桩承载力的50%左右,桩为端承摩擦桩,且桩的承载力较高,沉降变形小。

Through the static load test, the author carries out the experimental study of the pile bearing behavior in the silty clay, the experimental results demonstrates that the frictional resistant coefficients of the pile in the silty clay is 37.6 kPa, the frictional end resistance coefficients of the pile can reach 3.34 MPa, the end resistance of the pile in the silty clay account for 50% in the pile bearing behavior, the pile is the end-support friction pile and the bearing behavior of the pile is high, the settlement deformation is small.
