Abstract: Degree of compaction is an important index in quality control of channel filling, use cutting ring method to examine usually, but it have a long testing periodic time and destroy the embankment heavily. Based on the relationship, that tip resistance of variable energy dynamic penetrometer and degree of compaction, put forward a rapid testing method of degree of compaction detect. Which is use traditional cuttingring method to standardize the surveyed area, find a tip resistance correspond with the degree of compaction, and then use variable energy dynamic penetrometer to measure the embankment, according to the tip resistance evaluate the quality of the fill body. This method have a tiny damage to the fill body, and achieve the fast testing of the fill body which have many layers uninterrupted, satisfy the need of detection, have a broad application prospects.

Key words: variable energy dynamic penetrometer, channel, filling quality, Rapid testing
