振动挤密砂桩处理公路软土地基的原理与应用

摘要

This paper describes the strengthening mechanism of vibration compaction sand pile on soft soil,combined with the engineering practice,construction technology of vibrating compaction sand pile is introduced,and the corresponding quality control technology and the detection methods of treatment effect are put forward. The results show that the vibration compaction sand pile has the advantages of high density of the pile,obvious strengthening effect,simply constructing,low cost and so on. It is one of the practical methods to reinforce the soft soil foundation and it can provide reference for similar projects.%本文介绍了振动挤密砂桩处理软土地基的加固原理，并结合工程实践，提出该工程振动挤密砂桩的施工技术，同时提出相应的质量控制技术和处理效果检测方法，以期为同类工程提供参考。工程实践表明，振动挤密砂桩具有桩体密度大、加固效果显著、施工简洁、成本相对低廉等优点，是加固软土地基比较实用的方法之一。
