| 摘 要： | 全面分析南沙某真空预压区的监测成果,从土体的变形、孔隙水压的消散、水位的变化加固前后土层土工参数的变化、十字板试验等各方面评价了真空预压加固超软地基的效果,监测结果说明真空预压加固后,土体强度得到明显提高,工后沉降大大减少。

| Abstract: | This paper analyzes the observation results of a vacuum preloaded plot in Nansha. The soil deformation, pore water pressure dissipation, geological parameter variations following water level changing, and vane shear test results are taken intoconsideration toassess the effect ofvacuumpreloadingmethod. The observation results showthat the soil strength improves obviously, and the after- work settlement is greatly reduced after vacuum preloading. |
