The dynamic compaction tests with 8 000 kN m

6 000 kN m

4 000 kN m and 3 000 kN m energy-levels for treating desert soil in Inner Mongolia were carried out. And then through the standard penetration test

cone penetration test and the static plate loading test on the desert soil after dynamic compaction

for different levels of dynamic compaction of the desert area of fill areas

excavation zone after reinforcing

the respective effective treatment depths and bearing capacities of reinforcement are obtained. Some rules of dynamic compaction treatment on the desert soil are summarized; some construction parameters of dynamic energy level

effective reinforcement depth

spacing

etc. are given

so as to offer for reference in the similar geological conditions for the foundation treatment works with dynamic compaction.
