重塑黄土与植物根系界面摩擦离散元分析
DEM analysis of the remoulded loess and root system interface friction
摘要
Abstract
Pinus plays an important role in the reinforcement of loess strength because of its wide distribution in loess area.In order to investigate the fix-soil-effects of Pinus root system in loess area,a series of pull-out tests were carried out using the Distinct Element Method (DEM).The effects of normal stress,embedded depth and water content on the frictional mechanism of root-soil interface were analyzed.The results showed that,from the pull-out tests,the peak strength and residual strength of root-loess interface increased with the increases of normal stress and embedded depth,and with the decreases of water content.关键词
