摘　　要：随着我国建筑行业的不断发展,建筑用地的地质条件也愈发复杂多变。为了平整场地而采取的高挖低填措施往往带来高昂的地基处理费用,且处理效果较难评估。通过在深厚回填土层进行柱锤强夯配合多重原土置换的处理工艺,并采取平板载荷试验、标准贯入试验等检测手段对处理前后的地基土层进行分析与评价,结果表明该工艺能显著提高大厚度回填土层的物理力学参数,为类似的工程项目提供参考依据。With the development of construction industry,the geological conditions becomes increasingly complex and variable.It takes much costs in foundation treatments but the treatment effect is difficult to evaluate.Through the method of cylindrical hammer dynamic compaction combined with soil replacement,and using detection methods such as plate load test and standard penetration test to analyze and evaluate the foundation before and after treatment,the result shows that this process can significantly improve the physical and mechanical parameters of thick backfilled soil layers,providing a reference basis for similar engineering projects.
