摘要
桩基础顶部在受到竖向荷载作用时,荷载沿桩身向下传递的过程是通过不断克服桩侧摩阻力而向桩端传递的,这是个复杂的非线性过程。介绍了3种数学模型即理想弹塑性模型、双曲线模型和指数模型模拟桩土荷载传递的复杂非线性过程,并重点介绍了指数模型在实际工程中的应用。
When the top of the pile foundation bears vertical load, the pile body will transfer the load downward the pile by constantly overcoming the pile side frictional resistance. This process is a complex and nonlinear process. The article introduced three mathematical model, which is Ideal elasticplastic model, Hyperbolic model and Index model to simulate the complicated nonlinear load transferring process of the pile and soil. And the article mainly introduced the application of the Index mode in actual engineering.
