摘要
土工合成材料加筋土柔性桥台复合结构是美国近年提出针对于中小型单跨桥梁的新型结构,结构具有占地少、费用低、耗时短等优点,随着我国次级道路桥梁快速发展,此工程应用在我国具有极大发展前景。从理论研究、试验研究、数值模拟三个方面简述了土工合成材料桥台的研究现状,介绍了土工合成材料桥台设计方法,桥台的工作性能和影响工作性能因素的研究成果,并总结土工合成材料加筋土柔性桥台今后的研究重点。
The geosynthetics reinforced soil flexible abutment composite structure is a new type of structure for small and medium-sized single-span bridges proposed in the United States in recent years,which has the advantages of less occupation of land,low cost,short time and so on.With the rapid development of China's secondary road Bridges,this project of the structure has a great development prospect in China.In this paper,we studyed the research status of geosynthetics abutment from three aspects:theoretical research,experimental research and numerical simulation.Among these,we introduced the design method of geosynthetics abutment,the working performance of abutment and the research results of the factors affecting the working performance.Based on all this research status,we summarized the research emphases of flexible abutment reinforced with geosynthetics in the future.
