真空预压法在超软地基中的应用及效果分析

Application and Effect Analysis of Vacuum Consolidation Method in New Reclamation Saturated Silt Soil

项目采用土工布,竹筏和回填砂垫层建立工作平台,再采用真空固结方法对软弱地基进行加固,并结合监测数据对地基改良效果进行评价分析。结果表明,经过施工工艺改进,真空预压方法已成为可应用于各种复杂条件下的且经济有效的地基加固方法。

PVD installation and vacuum consolidation works can be done on the platform. Surface settle- ment plate, vacuum gauge are employed for monitoring. Load plate test and cone penetration test are used for e-valuating ground improvement effective performance. It was proved that the vacuum consolidation technique has become an effective and economical method for the soft ground improvement and capable to conduct in varioussite conditions by improving construction techniques.
