A New Classification System for Weathered Weak Rock Masses
(Techno-Press, 2026) Mao, Yimin; Nanehkaran, Yaser A.; Azarafza, Mohammad; Miao, Decheng
This research presents a new empirical rock mass classification system for sedimentary weak rocks, such as marlstones, taking into account the extent of weathering within the rock mass. For this purpose, 45 marlstone samples were systematically collected from the South Pars region in southwest Iran. The study involved measuring the geoengineering characteristics of the marls and assessing the degree of weathering they had undergone. The collected data was used to create variation weathering charts that show changes in rock mass durability and geoengineering properties with different degrees of weathering. These new charts are valuable tools for evaluating the condition of marlstone rock masses, providing a clearer understanding of how weathering affects their stability and durability. The empirical classification system introduced in this study significantly advances the assessment and management of marlstone formations in geotechnical engineering and related fields.
