摘要
香根草具有强大而快速生长的根系,因而特别适合于边坡加固,但是目前很少有关量化香根草根系固坡效果的研究.基于此,开展了根系现场调查和含根土取样,在实验室内进行了香根草根区土壤剪切试验和根系抗拉强度试验,试验结果的整体趋势验证了香根草根系固坡模型,该模型可用于评估香根草根系对土坡的加固效果.
Vetiver due to its powerful and fast growing root system,is highly suitable for slope stabilization.However,rare research work has been carried out for quantifying the stabilizing effect of vetiver roots on slopes.In this study,in-situ investigation of vetiver root system was conducted;undisturbed samples of soil and rooted soil were taken from the field;the shear strengths of the soil and rooted soil were determined in the laboratory by means of a standard shearbox tests;and the tensile strengths of the roots were measured using a universal testing machine,hence the root reinforcement model of vetiver was verified by the overall trend of the experiment results;this model can be used to assess the stabilizing effect of vetiver root system on soil slope.
