摘要
根据所提出的土工格栅与土动力相互作用分析模型 ,编制了加筋土的动力有限元分析程序G -D ,有限元分析结果与加州大学UCLA加筋挡土墙实测值一致 ,同时利用编制的分析程序对在路面下铺设土工格栅的道路模型和不加筋道路模型进行动力响应对比分析 ,研究在交通荷载作用下土工格栅的加筋效果 ,揭示了土工格栅与土动力相互作用机理 ,为实际工程提供理论依据。
Based on the interface model of geogrid-soil dynamic interaction, a procedure, named G-D, is proposed for computation of the dynamic response of reinforced soil. The FE analysis results agree well with the observed data including acceleration-time response from the UCLA reinforced soil retaining wall at the University of California. Finally, the dynamic response contrast analysis of the road model reinforced with geogrid and the unreinforced road model is studied in order to show the reinforement effect under the automobile loadings, and illuminate the principle of geogrid-soil dynamic interaction. Then, theoretical background is provided for engineering design and construction.
