某变电站地基处理方案分析

Analyze for Ground Treatment Scheme in Some Transformer Substation

根据２２０ｋＶ彩塘变电站的工程地质条件， 分析了几种可能的地基处理方法， 重点论述了振冲挤密砂桩的布桩型式、桩长、承载力与沉降验算。推荐采用振冲挤密砂桩是较为经济合理的一种方法。

Base on the geological condition,this paper analyzes some probably ground treatment methods,especially discusses pile form,pile length,bearing capacity and settlement of vibroflotation sand compaction pile.The vibroflotation sand compaction pile is an economical,reasonable ground treatment method,and it is recommended to use in this substation foundation.
