接触有限元模型在摩擦桩沉降计算中的应用

该文介绍了接触有限元模型在摩擦桩沉降计算中的应用。建立ANSYS有限元模型,计算软土地基中摩擦桩在竖向荷载作用下的沉降。该模型土层定义为弹性,以面面接触对模拟桩土接触面,温度荷载模拟土层对桩的侧压力。计算得Q-S曲线与试桩实测资料对比,结果表明,用该方法进行基桩沉降计算是有效的。

Application of Contact Finite Element Model in Calculation of Friction Pile Settlement

The article introduces the application of the contact finite element model in the calculation of the friction pile settlement.ANSYS finite element model is set up tO calculate the settlement of the friction pile in the soft soil subgrade under the vertical loading action.The soil layer of this model is defined as the elasticity.The face-face contact pair is used to simulate the pile soil contact face,and the temperature load is used to simulate the side pressure of soil layer to the pile.After the contrast of the calculated Q-S curve with the measured data of the trial pile,the result makes clearly that it is efficient to use this method to calculate the settlement of the foundation pile.
