强夯振动的频域分析

Frequency analysis of dynamic compaction vibration

强夯法是地基处理的重要方法之一。然而 ,强夯施工振动往往成为制约强夯法应用的关键问题。另外 ,作为一种能量可控的瞬态冲击荷载 ,强夯施工可以作为一个可控的土动力学原位试验。本文通过强夯振动频域分析 ,提出了介质作用函数和强夯激励函数的计算方法 。

Dynamic compaction is one of important methods for ground treatment.But the vibration during dynamic compaction often becomes a problem that restricts the application of dynamic compaction .On the other hand,as an instant impact load with controllable energy, dynamic compaction is a good test insitu for the study of soil dynamics.With the analysis in the field of frequency,computational method for mediumeffecting function and impelling function of dynamic compaction is put forward in this paper.
