离心模型试验的准确性与可靠性取决于模型与原型的相似程度，选择合理的相似材料是离心模型试验的关键环节。以广州某垃圾填埋场挡坝加筋边坡的工程设计为背景，为合理开展离心模型试验，选取6种编织布进行分析。考虑强度相似原则和界面摩擦因素，基于窄条拉伸试验、直剪摩擦试验合理比选相似替代材料。按该边坡设计方案，模型边坡在离心场中能够保持稳定。边坡设计中应进一步参照数值分析和工程类比进行方案确定。如按强度相似进行材料选择，通过调整模型土层厚度，所选择的6种材料可对抗拉强度在13~360 kN/m的土工布进行模拟。

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.
