Abstract

Kinematic analysis is a widely used method to assess stability condition in jointed rock slopes and predict the modes of block detachments. However, consideration of kinematic failures as crisp values (e.g., 0 for failure otherwise 1) in the conventional analysis is a limit to the susceptibility quantification. This paper has introduced novel methods based on the adjustment factors of slope mass rating (SMR) to quantify kinematic susceptibility of planar, wedge, and topple failure modes in terms of percentage/indices. Manual calculation of SMR is tedious and time-consuming, particularly when a large number of joints are involved. Hence, a method has been devised for the quantitative determination of both kinematic susceptibility and SMR with the help of a computer application. A computer application named EasySMR has been developed to automate and ease the calculation process. The application can incorporate a large number of joint data to provide convenient numeral, graphical and pie-chart interpretation of the kinematic susceptibility and SMR results. The algorithm has been validated with the results of 35 rock slopes from the Himalayan region, India. A few case studies have been presented to demonstrate the functionality of the program and enhanced capabilities which enables rigorous and accurate analysis of rock slope stability.

在新的计算机应用的帮助下，对节理岩质边坡运动稳定性和边坡质量等级进行定量分析的新方法

运动分析是一种广泛应用于节理岩质边坡稳定状况评估和块体分离模式预测的方法。然而，在传统的分析中，将运动失效考虑为清晰值(例如，失效为0，否则为1)是对易感性量化的限制。本文提出了一种基于边坡质量等级调整因子(SMR)的新方法，以百分比/指数来量化平面、楔形和倾倒破坏模式的运动易感性。人工计算SMR繁琐且耗时，特别是当涉及大量关节时。因此，在计算机应用程序的帮助下，设计了一种定量确定运动易感性和SMR的方法。已经开发了一个名为EasySMR的计算机应用程序来自动化和简化计算过程。该应用程序可以结合大量的联合数据，为运动敏感性和SMR结果提供方便的数字、图形和饼图解释。该算法已在印度喜马拉雅地区35个岩质边坡上进行了验证。一些案例研究已经提出，以证明该程序的功能和增强的能力，使岩石边坡稳定性的严格和准确的分析。

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
