基于试验资料及数值模拟方法,分析研究了桩端土强度对桩端附近侧摩阻力的影响。结果表明,高强度的桩端岩土层及较大的桩顶荷载,其桩侧摩阻力在桩端附近存在增强效应,同时,对该增强效应产生机理进行了解释。%Based on the test data and numerical simulation,the influence of soil strength at pile tip on pile shaft resistance was analysed and studied.It was shown that a so-called strengthen effect of pile shaft resistance would occur at pile tip for high strength
