Abstract

Shear strength (τ), shear stress (σs) and slope angle (β) plays a very important role in the stability of any soil slope. This research investigates the slope stability of a soil slope in order to determine correlations between shear strength with slope angle and shear stress. The assessment and calculation of the soil slope are carried out using slope stability analysis methods that assumed the failure surface as circular slip surface. A limit equilibrium software namely Slide and numerical modelling software namely Statistical Package for Social Sciences (SPSS) are used for the analysis. A total number of two hundred analysis are performed with varying slope angle of 70 to 88 degrees. Correlations are developed between τ, β and σs, which shows a very close relationship of all these three parameters. Applicability of the equations is above 97%. The correlations can be used in any slope stability project to know about the shear strength of the slope with variation in the value of slope angle and shear stress.

土坡分析，以开发在饱和和非饱和条件下有用的相关性

抗剪强度(τ)、剪切应力(σs)和边坡角(β)对任何土质边坡的稳定性起着非常重要的作用。为了确定抗剪强度与坡角和剪应力之间的关系，本文研究了土质边坡的稳定性。采用假定破坏面为圆滑面的边坡稳定性分析方法对土质边坡进行评价计算。极限平衡软件，即Slide和数值模拟软件，即社会科学统计软件包(SPSS)用于分析。共进行了200次分析，坡度从70°到88°不等。τ、β和σs之间建立了相关关系，表明这三个参数之间的关系非常密切。方程的适用性在97%以上。该关系式可用于任何边坡稳定工程，以了解边坡的抗剪强度随坡角和剪应力值的变化情况。
