An aircraft parks lies in a coastal region. There are deep silt stratification with high moister contents under the ground. The soft ground is treated with dynamic consolidation replacement.The test insitu, design of parameters and construction for this project are introduced in detail. The composite subgrade consolidated is inspected by drilling and geological radar. The settlement survey shows that the treatment for parks ground attains expected purpose.
