摘要
采用接触面单元模拟竖向荷载作用下桩与岩土间的粘结—滑移,提出了一种模拟嵌岩桩嵌岩深度效应的三维弹塑性有限元模型,指出计算模型能较好地反映接触面极限摩阻力及粘结刚度的影响,分析表明,在输入合理参数的前提下,该模型可用于分析确定嵌岩桩的合理嵌岩深度。
The characters of sticking and slipping of interface between pile and rock soil is modeled used interface element. One 3-D elasto-plastic finite element model for simulating effect of rock-socketed deep of rock-socketed piles has been presented. Presented model could embody limiting shaft resistance and sticking stiffness. The numerical analyses indicated that reasonable rock-socketed deep can be determined using presented model if inputting reasonable model parameters.
