含根量对SANDWICH形加筋土界面剪切强度影响
Effect of plant root content on interfacial shear strength of SANDWICH reinforced soil
摘要
Abstract
The mechanical properties of soil-reinforcement interaction are important for the design and stability analysis.A series of shear tests were performed to investigate the interface behavior of soil against geogrid with the effects of root content,normal stress and other factors.The results indicate that,the maximum shear stress at the interface of sandwich reinforced increase with the addition of root and the shear strength increases more with the increase of normal stress.With the increase of root content in the soil,the maximum shear stress of interface increases at first and then decreases under different normal stress.According to test data,an empirical formula for evaluating the shear strength is proposed by the fitting software,and the optimal theoretical value of root content is 4.2%.The validity and correctness of the fitting formula are verified by experiments.关键词
