摘要
首先介绍了塑料排水板(PVD)加固的软土地基固结沉降计算的分析方法。该方法中提出了塑料排水板加固地基的等效竖向渗透系数的概念与计算方法。并介绍了影响分析结果的四个参数的选取方法。通过一个工程实例介绍了路堤荷载下PVD 加固地基的有限元二维分析方法。结果表明所提方法可以较好地模拟实测数据。
An analytical method for prefabricated vertical drain (PVD) improved subsoil.is introduced. A concept of equivalent vertical hydraulic conductivity of PVD-improved subsoil with its calculation method was proposed. Then, the determination of parameters is introduced. Finally, the proposed method is applied to an engineering example. The results show that the proposed method can predict the measured data very well.
