基于弹性薄板理论的充填挡墙厚度新模型
New model of filling-retaining wall thickness based on theory of elastic plates
摘要
Abstract
In order to calculate the thickness of filling-retaining wall correctly, the height of once-filling and concrete tensile strength were chosen as factors. Based on theory of elastic plates, the mechanical model was built for thickness of filling-retaining wall reinforced, and the relationship between filling height, concrete tensile strength and thickness of retaining wall was deduced. Taking Jinchuan NO.2 mine as the example for engineering analysis, the rule of filling height, concrete tensile strength and thickness of retaining wall was studied by CVM. The result shows that the thickness of filling decreases with the increase of the concrete tensile strength, and shows 1/2 power relations with certain retaining wall size and physical and mechanical parameters of filling slurry. And the thickness of filling increases with the increase of the height of once-filling, and shows 1/2 power relations under constant concrete tensile strength. Comparing the results with the existing theory of filling-retaining wall thickness, the correctness and rationality of the mechanical model are verified.关键词
