| Abstract: | The applicability of the no-sand cushion vacuum preloading method is discussed here.The effect and technology of the method in unconsolidated soil are also studied through the field tests of Wenzhou hydraulic filling foundation engineering.The results show that this method is effective in improving the bearing capacity of ultra-soft foundation,and could be popularized in similar projects. |
