The Experimental Research about Vibration Compacting Load Transfer Spread in Roadbed

Abstract:

In this paper, the caustics method was used to explore the distribution of contact forces inside a packing of discrete square cells submitted to a compressive load. The self making subroutine 3-D generation algorithm about irregular particle generation and particle contact interface generation were adopted, and irregular particles were randomly generated in the designated categories with this algorithm. The vibration compacting load diffuse and transfer law with different media dense state were analyzed. The test results show that the vibration load caused the effective compaction region was changed vertical long axis oval into the level long axis oval. The study provides an idea to research and employs a new over-loading road which better repels tired retrogression under the dynamic load.
