Abstract

Dynamic consolidation is widely used in foundation reinforcement projects,but how to choose the ramming energy is still a difficult matter in foundation reinforcement project.The effects of ramming energy on the improvement of saturated hydraulic fill were studied.Here,different ramming energies were used in three fields with the same geological conditions of soil layer.It was compared the variations of the depth of pit with the numbers of drops and passes,the evolutions of pore pressure with time,the variation of the settlement of ground surface,and the variation of the lateral displacement along depth.The studies showed that there was an appropriate ramming energy.Besides,the results of static cone penetration tests,standard penetration tests and loading plate test were analyzed.Studies showed that ramming energy was an important factor in saturated foundation reinforcement project;there was an optimal ramming energy under which the consolidation of saturated foundation could achieve great effect.
- ramming energy,
- improvement effect,
- pore water pressure,
