一、引言强夯法是近年来迅速发展起来的一项新型的地基加固方法。它的特点是方法简单、易行,适用范围广,加固效果好,速度快、费用低。因此在建筑部门受到日益广泛的重视。强夯法是在极短的时间内对土体施加一个巨大的冲击能量,加荷历时一般只有几十毫秒。明显的,在这样瞬时的冲击荷载作用下,土体所表现的性 I. INTRODUCTION The strong-tanning method is a new type of foundation reinforcement method that has been rapidly developed in recent years. It is characterized by its simplicity, easy operation, wide application range, good reinforcement effect, high speed, and low cost. Therefore, it has received increasing attention in the construction sector. The dynamic compaction method applies a huge impact energy to the soil in a very short period of time. It usually takes only tens of milliseconds to complete the loading process. Obviously, the performance of the soil under such transient impact load
