摘　　要：为了在理论上采用一种合理分析基桩动测承载力的方法,应用有限差分数值计算方法和波动理论,并基于Bowles方法的基础上,对该分析方法进行改进,采用FORTRAN软件编写分析程序计算基桩动测承载力。通过试验实例计算分析,得出该程序计算结果与静载试验结果基本吻合,说明采用该方法分析基桩动测承载力具有一定的合理性,对预测基桩动测承载力具有一定的使用价值。In order to adopt a reasonable method to analyze the dynamic bearing capacity of foundation piles in theory,the finite difference numerical calculation method and wave theory are applied.Based on the Bowles method,the analysis method is improved.The FORTRAN software is used to compile the analysis program to calculate the dynamic bearing capacity of foundation piles.Through the calculation and analysis of the test example,it is concluded that the calculation results of the program are basically in agreement with the static load test results.It is proved that the method is reasonable to analyze the dynamic bearing capacity of foundation piles,and it is valuable to predict the dynamic bearing capacity of foundation piles.
