摘要
采用轻便式直剪仪，对黄土高原几种土壤的浅层原状土抗剪强度进行现场测定，得出其抗剪强度指标的变化规律。通过对其影响因素分析，并与同类地区扰动击实土的抗剪强度进行比较，指出黄土高原地区浅层原状土其抗剪强度的脆弱性及其在水土保持坡面工程中的防治措施。
The antishear strength of several shallow original state soil was tested useing the instrument of handle direct shear in loess plateau, obtained the target and the law of change of antishear strength, pointed out the frailty of the antishear strength of shallow original state soil and the protective measures in the control of soil and water conservation on slope in loess plateau by analysing the affective factor of antishear strength and compared the antishear strength of original state soil with that of the disturbed hit solid soil.
