某加筋土边坡离心模型试验相似材料研究
Similar Materials in Centrifugal Model Tests on a Reinforced Soil Slope
摘要
Abstract
The accuracy and reliability of a centrifuge model test depend on the similarity between the model and the prototype.Selection of a reasonable similar material is a key procedure of the centrifuge model test.The background of this study is the engineering design of a retaining dam for garbage deposit in Guangzhou City.A total of six types of woven-cloth were analyzed for the rationality of centrifugal model test.In consideration of strength similarity and interface friction factors,the similar materials were selected based on narrow strip tensile tests and frictional direct shear tests.According to design scheme,the model slope remains stable in the centrifugal field.Numerical analysis and engineering comparison should be taken into account to determine the design scheme.According to strength similarity,the selected materials can be used to simulate geotextiles with 13-360 kN/m tensile strength via adjusting the compacted thickness of each soil layer.关键词
