A practical engineering on deep fill treated by dynamic consolidation is introduced in this paper,especially, the design parameters,construction, and effect observed are briefly discussed and analyzed.

This thesis is completed on the basis of the Ministry of Railways complex test--the study for different fill depth on the cover slabsof the culverts on Qinhuangdao-Shenyang dedicated passenger line.

Application of strengthen ramming in dealing of soil foundation deeply filled

The test results of the deep backfill strengthened by high efficiency dynamic compaction show this technology is feasible and can be the reference for the similar engineering.

By researching the curves of pile diameter,Q-s curves and the internal force curves of two impact-cone concrete piles,the influence of varying pile diameter on the bearing capacity and load transfer mechanism of the rock embedded short pile with post-grouting technology in deep sandstone filling soil area were discussed in the paper.
