| Abstract: | At present. the tube sinking compacted gravel pile has been widely used in ground treatment. As for applying it to soft soil area. the bearing capacity of the cornposite foundation is rather low. but can be further increased by water-filling preloading. which may broaden the application scope of compacted gravel pile. The strenthening effect being manifested by engineering practical examples. |
