Study on Model Test and Consolidating Mechanism of Piles Thrusted-Expanded in Column-Hammer
Method of piles thrusted-expanded with column-hammer is a ground treatment method which has Chinese characteristics. In order to study the consolidating mechanism of the ground treatment method, indoor model tests of thrusting hole and tamping pile are carried on and the consolidating mechanism is studied. At the same time, the influence factors of thrusting hole and tamping pile, such as the different tamping energy and diameter of column-hammer, are analyzed. The analysis results indicate that thrusting hole by column-hammer has the effect of lateral compacting and strongly tamping at the bottom of hole. In the tamping piles by column-hammer, the effect of expanding the bottom of pile and secondary compaction are very great. The conclusions will provide the technology basis for the optimizing the design of the ground treatment method.
