强夯法改进冲洪砂卵石地基的试验研究与数值分析

Experimental Study and Numerical Analysis of Improving Ramming Sand and Gravel Foundation by Dynamic Compaction

本文主要结合目前世界技术水平最先进的特高压直流输电工程实例中所解决的冲洪砂卵石层地基强夯处理问题,并运用压实系数检测试验、重型动力触探试验和平板荷载试验三种数据分析方法对施工项目地基加固效果给出了准确的结果分析和评价。从而有效的保障了施工项目达到国家相应标准,同时为同类型施工项目提供了减少施工工期与成本的方法思路。

This paper gives a result analysis and evaluation of the foundation consolidation effect of the construction project by three data analysis methods of compaction coefficient test, heavy - duty dynamic penetra- tion test and plate load test, combining with the strong foundation treatment of impulse sand and gravel layer which is solved in the case of the most advanced UHV DC transmission project in the world. So as to it protects the construction project effectively to meet the corresponding national standards, and it provides a method to re- duce the construction time and cost for the same type of construction projects as well.
