摘　　要：加筋土挡墙具有绿色环保、造价低廉、性能良好等优势,在国内外得到了广泛应用,研究人员对其进行了大量的研究。在加筋土挡墙结构设计方面,现有规范规定的台阶宽度设计偏于保守,对于最小筋材长度的研究也尚未得出统一结论,有待进一步完善。在加筋土挡墙物理性能研究方面,筋-墙连接与筋-土界面摩擦所导致的筋材受力不均问题需重点探究;挡墙潜在破裂面受多种因素影响,通过筋材峰值应力应变来预测挡墙潜在破裂面位置及形状的思路值得肯定,但仍存在准确性不足的问题;更准确、系统的挡墙土压力、极限承载力、侧向变形理论方法尚未形成,需要进一步研究。Reinforced soil retaining walls have the advantages such as green environmental protection,low cost and good performance,and have been widely used at home and abroad.Many researchers have conducted extensive studies on them.In terms of the structural design of reinforced soil retaining walls,existing specificationsfor step widths design tend to be conservative,and there has yet to be a unified conclusion on the research of minimum reinforcement length,which requires further improvement.Regarding the physical performance of reinforced soil retaining walls,the issue of uneven force on the reinforcement due to the reinforcement-wall connection and reinforcement-soil interface friction needs to be explored in depth.The potential rupture surfaces of the walls are influenced by various factors.The approach of predicting the location and shape of these potential rupture surfaces based on the peak stress-strain of the reinforcement is commendable,but it still lacks accuracy.More accurate and systematic theoretical methods for wall soil pressure,ultimate bearing capacity,and lateral deformation have yet to be developed and require further research.
