中文摘要:西北某回填湿陷性黄土地基强夯处理项目，施工完成后部分区域土层湿陷性未完全消除。对强夯法加固回填湿陷性黄土地基有效加固深度的影响因素进行分析，认为夯击能量和夯击次数是影响有效加固深度的首要因素，此外还有地基土含水量、不同土层的厚度及埋藏顺序、回填土层的密实程度及强夯设计参数等。

Analysis on Influencing Factors on Effective Reinforcement Depth by Dynamic Compaction Method in Backfill Collapsible Loess Foundation
Abstract:In a project of backfill collapsible loess foundation in the Northeast, some regional soil collapsibility was not completely eliminated. Analysis is made on the influencing factors on effective reinforcement depth by dynamic compaction method in backfill collapsible loess foundation, the first influencing factors are determined to be the consolidation energy and one-shot points, and the soil moisture content, the thickness and distribution of different soils, compaction rate and the dynamic compaction design factors should also be considered.
