桩侧摩阻力随位移发挥的实测分析

Measured Analysis for Mobilization of Pile Shaft Resistance with Local Displacement

该文主要讨论侧摩阻力随位移的发挥性状。在对双曲线模型进行分析的基础上,采用这一模型,对上海地区某预制桩的侧摩阻力实测资料进行了分析。分析结果表明,采用双曲线函数模拟桩侧摩阻力随相对位移的发展变化是合适的。依据实测资料,给出了上海土层侧摩阻力随位移发挥的双曲线模型参数。

The article mainly discusses the mobilization of pile shaft resistance with local displacement. On the basis of analyzing the hyperbolic model, this model is used to analyze the measured shaft resistance data of a prefabricated pile in Shanghai. The analysis result makes clearly that it is suitable to use the hyperbolic function model to simulate the development and variety of pile shaft resistance with local displacement. The hyperbolic model parameters of shaft resistance with local displacement mobilization of soil course in Shanghai are given on the filed measured data.
