摘要
总结已有文献对受土洞塌陷影响下土工合成材料的受力特性、挠曲变形研究成果,重点阐述受土洞塌陷影响下加筋路基的作用机理,分析加筋路基的荷载传递机制及沉降变形特性,介绍单层加筋体系及多层加筋体系的设计理论,并针对现有研究的不足提出建议。
The research achievements on the stress characteristics and flexural deflection of geosynthetics under the effect of soil cave collapse in the existing literature were summarized herein.The emphasis was laid on the explanation of action mechanism of reinforced subgrade affected by soil cave collapse,and the analysis of load transfer mechanism and settlement deformation characteristics of the reinforced subgrade,and then the design philosophy of single-layer and multi-layer reinforcement system were introduced.There are some suggestions were put forward to address the gaps in existing research.
