    Improved Prediction of Slope Stability under Static and Dynamic Conditions Using Tree-Based Models

    Feezan Ahmad1, Xiaowei Tang1, Jilei Hu2,*, Mahmood Ahmad3,4, Behrouz Gordan5

    CMES-Computer Modeling in Engineering & Sciences, Vol.137, No.1, pp. 455-487, 2023, DOI:10.32604/cmes.2023.025993

    Abstract Slope stability prediction plays a significant role in landslide disaster prevention and mitigation. This paper’s reduced error pruning (REP) tree and random tree (RT) models are developed for slope stability evaluation and meeting the high precision and rapidity requirements in slope engineering. The data set of this study includes five parameters, namely slope height, slope angle, cohesion, internal friction angle, and peak ground acceleration. The available data is split into two categories: training (75%) and test (25%) sets. The output of the RT and REP tree models is evaluated using performance measures including accuracy (Acc), Matthews correlation coefficient (Mcc), precision… More >

    Developments and Applications of Neutrosophic Theory in Civil Engineering Fields: A Review

    Zhenhan Zhang, Jun Ye*

    CMES-Computer Modeling in Engineering & Sciences, Vol.135, No.2, pp. 887-916, 2023, DOI:10.32604/cmes.2023.022961

    Abstract Neutrosophic theory can effectively and reasonably express indeterminate, inconsistent, and incomplete information. Since Smarandache proposed the neutrosophic theory in 1998, neutrosophic theory and related research have been developed and applied to many important fields. Indeterminacy and fuzziness are one of the main research issues in the field of civil engineering. Therefore, the neutrosophic theory is very suitable for modeling and applications of civil engineering fields. This review paper mainly describes the recent developments and applications of neutrosophic theory in four important research areas of civil engineering: the neutrosophic decision-making theory and applied methods, the neutrosophic evaluation methods and applications of… More >

    Effect of Inclined Tension Crack on Rock Slope Stability by SSR Technique

    Ch. Venkat Ramana*, Niranjan Ramchandra Thote, Arun Kumar Singh

    Intelligent Automation & Soft Computing, Vol.36, No.1, pp. 1205-1214, 2023, DOI:10.32604/iasc.2023.031838

    Abstract The tension cracks and joints in rock or soil slopes affect their failure stability. Prediction of rock or soil slope failure is one of the most challenging tasks in the earth sciences. The actual slopes consist of inhomogeneous materials, complex morphology, and erratic joints. Most studies concerning the failure of rock slopes primarily focused on determining Factor of Safety (FoS) and Critical Slip Surface (CSS). In this article, the effect of inclined tension crack on a rock slope failure is studied numerically with Shear Strength Reduction Factor (SRF) method. An inclined Tension Crack (TC) influences the magnitude and location of… More >

    Reliability Analysis of Slope Stability Considering Temporal Variations of Rock Mass Properties

    Xin Gu2, Lin Wang1, 2, 3, Fuyong Chen2, Hongrui Li2, Wengang Zhang1, 2, 3, ∗

    CMC-Computers, Materials & Continua, Vol.63, No.1, pp. 263-281, 2020, DOI:10.32604/cmc.2020.07535

    Abstract Temporal variation of rock mass properties, especially the strength degradation due to drying-wetting cycles as well as the acidic wetting fluid (rainfall or reservoir water) is crucial to stability of reservoir rock slopes. Based on a series of drying-wetting cycling and experiments considering the influences of pH values, the degradation degree models of the reduced cohesion c′, friction angle φ′ are developed. 2D stability analysis of the slope is subsequently carried out to calculate the factor of safety (Fs) via limit equilibrium method (LEM) and a predictive model of Fs is built using multivariate adaptive regression splines (MARS), revealing the… More >

    Kinematic Analysis and Rock Mass Classifications for Rock Slope Failure at USAID Highways

    Ibnu Rusydy1,3,*, Nafisah Al-Huda1,2, M. Fahmi4, Naufal Effendi4

    Structural Durability & Health Monitoring, Vol.13, No.4, pp. 379-398, 2019, DOI:10.32604/sdhm.2019.08192

    Abstract Rock slope kinematic analysis and rock mass classifications has been conducted at the 17th km to 26th km of USAID (United States Agency for International Development) highway in Indonesia. This research aimed to examine the type of rock slope failures and the quality of rock mass as well. The scan-line method was performed in six slopes by using a geological compass to determine rock mass structure on the rock slope, and the condition of joints such as persistence, aperture, roughness, infilling material, weathering and groundwater conditions. Slope kinematic analysis was performed employing a stereographic projection. The rock slope quality and… More >

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.16, No.2, pp. 49-50, 2011, DOI:10.3970/icces.2011.016.049

    Abstract This paper is to study the stability of jointed rock slope using the Goodman joint element and upper bound limit analysis. Assumed the constitutes of rock masses, rock block and joint, obey perfect rigid plasticity and Mohr-Coulomb yield criterion, an upper bound finite element formulation is build to study the stability analysis of jointed rock slope using the Goodman joint element.
