针对新近吹填砂性土地基的地表覆盖层下存在较厚淤泥质软土夹层的情况，结合工程设计和施工实践探讨加塑料排水板的强夯法地基加固处理新工艺，实践证明在合理选用强夯工艺参数的情况下，该方法对加固饱和软粘土地基是可行，且比传统的堆载预压法、碎石桩法等加固方案更经济，在缩短工期方面具有明显的优势。%Thicker muddy soft soil interlayer is found underground covering layer of sandy soil foundation which is dredger-filled recently. In that case, a new foundation reinforcement technology is discussed in the aspect of engineering design and construction, i.e. dynamic compaction method being combined with plastic drains. Engineering practice proves that the above method can reinforce the saturated soft clay foundation effectively subject to the selection of reasonable dynamic compaction parameters. Compared with conventional preloading method or gravel pile reinforcement method, the dynamic compaction method is of obvious advantages in cost and shortening construction period.
