A new soft base reinforcement technique had been tested in Tianjin Lingang Economic area with the engineering area reaching up to 50 000 m2. For instance,the pressurized vacuum preload method which vacuumized and pressurized the soil simultaneously in order to drain quicker,hand-joints were used in connection of drains and drainage tubes instead of traditional sand cushion,anti-clogging drains were adopted in soil with high water content and fine sediment particles to avoid the clogging. The test results show that the above techniques are effective and can be referred to in similar projects.
