摘要
为了确定房渣土地基的有效加固深度,结合北京园博园水质净化工程地基处理试验工程实例,通过标准贯入试验、孔内波速测试、不同深度多点位移监测等检测方法对比分析,探讨了强夯法加固房渣土地基的有效加固深度。结果表明:可选用多点位移监测结合标贯试验的方法综合判定房渣土地基强夯有效加固深度。研究成果对于类似强夯地基处理工程具有参考价值。
In order to determine the effective reinforcement depth of miscellaneous fill foundation,the effective reinforcement depth of the miscellaneous fill foundation reinforced by dynamic compaction is discussed herein through the detection methods,i.e.standard penetration test,down-hole wave velocity test,different depth multi-point displacement monitoring,etc.in combination with the actual case of the experimental project of the foundation treatment for Beijing Garden Expo Park’s water purification project.The result shows that the method of multi-point displacement monitoring combined with standard penetration test can be selected for comprehensively judging the effective reinforcement depth of miscellaneous fill foundation made by dynamic compaction.This study result has a referential value for the similar project of foundation treatment with dynamic compaction.
