本文系统梳理了目前土壤抗剪强度的几种主要测定方法,相关影响因素及其与土壤侵蚀之间的关系研究现状,分析了现有研究中存在的问题,提出今后研究应在确定统一抗剪强度影响因素评价指标基础上,加强土壤抗剪强度与土壤水蚀、风蚀之间的相关关系的定量研究.
Soil shear strength is the maximum force soil could stand before fracture occurs; it is an important index of soil mechanical properties. Many soil erosion experts are involved in research of soil shear strength in recent years, with a focus on influence factors and correlation to erodibility. Major assays of soil shear strength, affecting factors, correlation with soil erosion, deficiency in existing research are all reviewed. Research trends for the future are explored. It is proposed that future research unify evaluation index of influence factors of shear strength, and strengthen quantitative research on correlation between soil shear strength, soil water and wind erosions.
