一、原理 强力夯实法(简称强夯法)起源于法国,1969年首次用于法国戛纳附近芒德利厄海边20多幢八层建筑物的地基加固工程。用后效果很好,立即引起了人们的注意和重视,最初是用于砂砾石地基,随后又推广到饱和粘性土与冲积土地基。法国人梅那(L.Menard)根据饱和粘性土经受强夯于瞬间产生数十厘米沉降的现象,提出了一个新的动力固结理论(图1),其机理如下。
First, the principle Powerful compaction method (referred to as dynamic compaction method) originated in France, 1969 for the first time in Cannes, France, near the Sea of Mandrelie more than 20 eight-storey building foundation reinforcement project. Very effective after use, immediately aroused people’s attention and attention, initially used for sand and gravel foundations, and later extended to saturated clay and alluvial soil foundation. According to L. Menard, a new theory of dynamic consolidation based on the phenomenon of saturated clayey clay subjected to tens of centimeters of settling at an instant (Figure 1), the mechanism is as follows.
