Coarse Grained Soil Consolidation Effect By Dynamic And Key Parameters

Dynamic Consolidation has become a generally accepted ground improvement technique for its simplicity and cost-effectiveness, has found wide applications since it was discovered. Especially in coarse particles foundations, with other methods of treatment are unrivalled. Dynamic consolidation of the foundation to further improve soil strength, reduce compressibility, eliminate the uneven settlement, to improve the physical and mechanical properties of foundation has obvious effect. Based on the analysis and conclude of the dynamic compaction technology. Put forward the dynamic consolidation foundation simplified model. Deduce the formulas for calculating instant-dynamical. Combined with the engineering practice, the paper from the dynamic compaction of reinforcing effect and influence factor is analyzed. The paper achieved the following conclusion.1,This paper using dynamic consolidation foundation simplified model in coarse particles foundations. And on this basis, build the formulas for calculating instant-dynamical.2,In the paper, after the dynamic consolidation, the bearing capacity of foundation and compression modulus increase is analyzed, summarized different soil types of relevant experience formula.3,Analysis the soil parameters and construction parameter effects of dynamic consolidation. Through the field test data collection and filing, use stepwise regression. Use the curve fitting between the soil parameters and construction parameters before dynamic consolidation and the bearing capacity of foundation and compression modulus after dynamic consolidation. Though the related data for a curve fitting and get the corresponding empirical formulas.4,Combined with the engineering practice, estimate the bearing capacity of foundation and compression modulus after dynamic consolidation. Through the field test, detect reinforcement effect after dynamic consolidation.
