土工格栅与尾矿拉拔试验及筋材拉力研究
Pull-out Test and Tensile of Geogrids and Tailings
摘要
Abstract
In order to analyzed the change law of tension along geogrid in the pull-out test of geogrid and tailings.Through the relationship between the tensile force, the shear stress and the strain of geogrid in the test.The tension coefficient a which affected the interface characteristics of geogrid and tailings was proposed.The distribution formula of tension along geogrid was derived, and the feasibility of the formula was verified by the measured data.In the reinforced tailings structure, when the pull-out displacement of reinforced material was not very large, this formula could be used to predicted tensile of geogrid in different positions.The results provided the basis for the application of geogrid in reinforced tailings dam.关键词
