| 摘 要： | 强夯置换的应用已逐渐广泛，但其设计是高度经验性的。强夯置换的理论研究较为肤浅，特别是置换深度的计算尚无较好的方法。为此，提出了模拟夯击过程的一维波动方程理论模型；初步建议了模型中有关参数的取值并用工程实例进行了验证；用所提出的模型探讨了置换体形成与扩展的基本规律；给出了应用的简化形式。结果表明，一维波动方程法及其简化形式与实际吻合较好，可应用于强夯置换的置换深度估算。

| Abstract: | Dynamic replacement has gained wide application, but its design is highly empirical. There is no way to estimate properly the displacement depth. In this event, this paper draws its attention on this subject, proposes a one dimensional wave equation model and its solution method for the replacement depth estimation, and gives the values of the parameters in this model for reference. Case studies showed this model is satisfactory. Thereafter, the replacement process has been simulated and a simplified formula for the replacement depth estimation is presented. |
