沿海蚝塘回填区地基真空预压加固效果分析

Analysis of consolidating effect by vacuum preloading to backfilled area foundation of coastal oyster ponds

结合珠海某蚝塘回填区真空预压软基处理工程,从现场监测和检测两方面分析了地基加固效果,结果表明:真空预压后,残余沉降、承载力均达到设计要求,软土各项指标明显改良,真空预压效果良好。

Combining with a soft soil engineering by vacuum preloading at backfilled area of coastal oyster ponds in Zhuhai,the reinforcement effect was analyzed from site monitoring data and testing results.The results showed that the residual settlement and bearing capacity reached the design requirements after consolidation by vacuum preloading,the physical mechanical indexes of the soft clay were improved obviously,the vacuum preloading consolidating effect was fine.
