Shuitu Baochi Xuebao[目的] 为研究根土复合体破坏全过程的本构关系。[方法] 以不同生长阶段的香根草(20,40,60天)和红壤的原状根土复合体为对象,基于邓肯—张模型,结合三轴试验,构建根土复合体破坏全过程的应力应变本构关系模型,并分析模型参数对根系生物量变化的响应。[结果] (1)邓肯—张本构关系模拟根土复合体力学行为的效果理想,除个别素土的应变软化现象不能捕捉外,应力应变曲线、抗剪强度指标的预测值与实测值均表现出高度的相关性(R2>0.91),并且能够很好地预测曲线在弹性阶段、硬化阶段和塑性阶段的变化特征。(2 ...

子午岭林区浅层滑坡侵蚀与植被的关系 ———以富县“7·21”特大暴雨为例
, 2016 以2013 年陕北富县“7·21”特大暴雨滑坡侵蚀灾害为对象，通过调查暴雨侵蚀区典型小流域植被条件及滑坡特征，测定 滑坡壁不同土层的根系重量、土壤孔隙度、土壤容重等指标，研究子午岭林区暴雨滑坡侵蚀与植被根系的关系。根据不同类型 植被根系深度和滑坡侵蚀特征( 侵蚀深度、滑动面宽度及长度，滑坡体体积、滑动距离等) ，可将林区暴雨滑坡侵蚀划分为三类: 以草本植被为主的A 类滑坡，以灌丛植被为主的B 类滑坡，以乔本植被为主的C 类滑坡。结果表明，三类滑坡侵蚀的侵蚀深度 ...
