| 摘 要： | 在对强夯作用分析的基础上，建立了双层地基在强夯荷载下的一维固结方程；利用Laplace变换给出了土层内有效应力的解析解，提出了土层固结变形量的计算方法。由所推导出的公式可以看出，有效应力和固结变形量与土层的性质有很大的关联，说明考虑实际地基的分层是必要的。同时，也揭示了强夯法加固成层地基的机理。

| Abstract: | Based on the analysis of dynamic impacts,the onedimensional consolidation's equation of double-layered ground under dynamic impacts is established,and the general solution of the effective stress of stratum is given by using Laplace transformation,then a method for calculating the consolidation deformation of stratum is proposed.From the formulae,it can be seen that the effective stress and consolidation deformation are related with properties of stratum.It is therefore necessary to consider the layered ground.At the same time,this also explains the principle about improving layered ground with dynamic impacts. |
