多道瞬态瑞雷波法在地基强夯质量检测中的应用探讨

The Application of Multi-channel Transient Rayleigh Wave on the Quality Examination of the Dynamic Compaction Foundation

为了提高地基承载力,减少填土的不均匀沉降,对软土地基进行强夯加固是一种十分经济有效的地基处理方法。在沿海地区,填海工程和低丘整平地基处理中,大量使用强夯法。因此,强夯地基效果的检测十分重要。本文通过对多道瑞雷波法理论以及在强夯地基检测应用效果的探讨,采用加权平均值法统计各测试点地基土的承载力特征值,对整个测区的强夯效果进行全面评价。

In order to improve the bearing capacity of filled soil foundation, reduce the uneven subsidence of soft soil foundation, dynamic compaction is a very economic and effective method. In coastal areas, we always use dynamic compaction method for sea reclamation. Therefore;the survey of dynamic compaction effect is very important. This paper discusses the theory of multi-channel transient Rayleigh wave and its application effect on the dynamic compaction foundation, and uses the weighted average method to calculate the characteristic value of foundation bearing capacity; last evaluates the dynamic compaction effect of the whole study area.
