将桩土模型简化成一个质量弹簧体体系,用稳态机械阻抗法测定单桩竖向承载力。计算承载力的关键,就是动刚度的测试精度问题。在进行动刚度计算时,引入更精确数学公式,在准确的试验测试数据的基础上,可取得更快捷、更准确的计算结果。 The pile-soil model is simplified into a mass-spring system. The steady-state mechanical impedance method is used to measure the vertical bearing capacity of single pile. The key to calculating the bearing capacity is the testing accuracy of dynamic stiffness. In the calculation of dynamic stiffness, a more accurate mathematical formula is introduced to obtain faster and more accurate calculation results based on accurate experimental test data.
