| Abstract: | Soft ground treatment affects the quality, investment and progress of the whole project, and its importance has been recognized by more and more people. Based on the principle of three-dimensional drainage consolidation and the pull-out force of the pile itself, the 3-D consolidated cylinder was used for once-for-all rapid drainage consolidation of saturated soft ground without external load, improving the shear strength, compression behavior, water permeability and dynamic characteristics of ground. |

| Keywords: | drainage consolidation pile reaction force once-for-all surcharge-free preloading 3-D consolidating cylinder soft ground |
