Construction of Clay Inclined Core Dam Reservoir Based on Fill Technology
In this study,based on the construction of clay inclined core dam reservoir with fill technology,the influence of different soil thickness and rolling times on dry density and compaction degree and the experimental analysis of permeability coefficient of clay inclined core dam were discussed.Through the experiment,it is found that the combination of laying soil thickness of 30cm and rolling 8 times has excellent performance in terms of dry density and compactness,which meets the design requirements of reservoir engineering.Therefore,this combination is studied as the best plan for filling clay core wall materials.The maximum permeability coefficient of the single ring method in red clay is 7.0×10-6,so using the single ring method to control the permeability coefficient can better reflect the permeability performance of the core wall under actual construction conditions.
