| Abstract:By the case of tamping test of dynamic compaction ground treatment with gravel and soil backfill in Laiwu 1000MW class power unit of Huaneng power plant, the construction quality difference and the treatment effects in 2 trial tamping areas with different construction processes are compared. On this basis, the construction quality, effective consolidation depth, soil compactness, deformation parameters and bearing capacity of the ground are found. According to the field tamping and backfill depth, the pre-placed depth and corresponding construction process are selected to determine the final construction plan for the further improvement of effect in dynamic compaction ground treatment, which provides an effective basis for large-area dynamic compaction with backfill and the finalized construction process. |
