强夯法是处理软弱地基的一个有效方法。1978年以来,我国开始了试验研究和工程应用,对多类土都取得了良好的效果。但能否应用于淤泥质土,还有争议。本文根据淤泥质土强夯试验时地基变形的量测结果,对强夯法处理淤泥质土的基本原理和一些规律进行了探讨。指出强力务击时淤泥质土的动力固结作用是明显的;只要施工方案合理,措施可靠,强夯法加固淤泥质土是有一定效果的。

The tough trick is an effective way to deal with weak foundations. Since 1978, China has started experimental research and engineering applications, and has achieved good results for many types of soil. However, it is still controversial whether it can be applied to muddy soils. Based on the measurement results of ground deformation during the test of muddy soil strength, this paper discusses the basic principles and some laws of the treatment of muddy soil by the dynamic compaction method. It is pointed out that the dynamic consolidation of muddy soil is significant when it is strongly attacked; as long as the construction scheme is reasonable and the measures are reliable, the consolidation of muddy soil by dynamic compaction method has certain effect.
