Abstract

This study presents an innovative application of force-energy equilibrium analysis to evaluate failure extension lengths (FEL) in excavation-induced translational landslides. Utilizing a combination of field data, mechanical balance analysis, and numerical simulations, we systematically investigate the effect of excavation on landslide dynamics. Our approach incorporates the existing energy balance framework and extends its application to excavation-induced translational landslides characterized by weak interlayer. The methodology focuses on capturing the intricate interplay between unloading forces, shear displacement, stress, and strain across various stages of landslide development. A case study of the Tongzilin landslide in Yanshan Township serves as a practical example, underpinning the validation of our theoretical model with real-world data. The proposed methodology provides a valuable reference for the prevention and management of excavation-induced translational landslides.

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.
