摘　　要：有限空间加筋土挡墙是一种筋材铺设长度小于规范要求的加筋土挡墙,该新型结构在保留常规加筋土挡墙优点的同时又弥补了施工空间受限的缺点,在山区道路建设或既有道路拓宽等领域具有广阔的应用前景。从理论研究、模型试验、数值模拟、现场试验等4个方面简述了有限空间加筋土挡墙现有研究现状。介绍了该新型挡墙结构的土压力分布、破坏模式、潜在破裂面形式、提高稳定性措施等方面的研究成果,并总结了有限空间加筋土挡墙今后的研究重点,以推广有限空间加筋土挡墙的发展与应用。The laying length of reinforced material of the limited space reinforced soil retaining wall is less than that of the specification requirements.This new structure retains the advantages of conventional reinforced soil retaining wall while compensating the shortcomings of the limitations of construction space,which could be used to road construction in mountainous areas or widening construction of existing roads etc.In this paper,the research status of reinforced soil retaining walls in confined space is briefly described from theoretical research,model test,numerical simulation,and field experiments,the research results of it in terms of earth pressure distribution,failure mode,potential fracture surface form,and stability improvement measures are introduced,and the future research focus of it is summarized,aiming to promote the development and application of the limited space reinforced soil retaining wall.
