Shuitu Baochi Xuebao, 2022 以昭通烂泥箐滑坡源区优势物种鸢尾科鸢尾属鸢尾原生根系—土复合体作为研究对象，采用直剪试验对复合体抗剪特征进行深入研究，并与室内相同含水率重塑复合体试验结果对比分析。结果表明，整体上无根素土具有应变软化特征，而复合体具有应变硬化的特性，各复合体的抗剪强度均比素土的高，且抗剪强度随着含根量的增加而增加，根系加固效应明显，但复合体并没出现与重塑土类似的最优（最佳）含根量。原状复合体的c值随含根量的增加没有明显变化规律，而φ值则逐渐递增，其增长率也有相同的变化趋势。复合体破坏断面显示根系为主根系且垂直贯通剪切面，

, 2021 越来越多的研究表明,在降雨条件下植物根系分布是影响边坡稳定的重要因素。为研究不同类型根系对边坡稳定的影响,开展了室内模拟降雨实验,分析不同类型植物根系影响边坡稳定的模式,探讨根系特征尺寸和分布的影响机理。实验结果表明:坡体上不连续分布的尺寸较小的孔洞,在土体变形过程中很容易自动封闭、堵塞,不易形成新的局部破坏;粗根系木本植物对于坡体稳定性具有不利的影响,在植物根部与土体接触的位置最容易产生局部破坏;草本植物根系对土体有显著的固化作用,并且其固化作用有一定的影响范围;植物根系对边坡的影响 ...
