高土石坝筑坝材料的力学特性及长期变形规律研究

Key Points

• The study aims to analyze the mechanical properties and long-term deformation behaviors of materials used in high earth-rock dams.
• Reviewed mechanical characteristics of common dam materials like rockfill and filter materials.
• Analyzed nonlinear behavior, stress dependence, and time-dependent deformation mechanisms.
• Explored constitutive models defining the mechanical behavior of these materials.
• Findings highlight the influence of time-dependent rheological deformation on long-term settlement and crack risk.
• Established that advanced constitutive models must accurately represent complex mechanical behaviors.
• Future research should integrate multi-source monitoring data for improved safety assessments.
