寒区土坝干砌石护坡损坏原因分析及设计对策OA

This paper systematically analyzes the causes of damage to upstream dry-laid stone slope protection of earth dams in cold regions and proposes a method for calculating the safety factor of such slope protection structures under ice uplift forces.A new type of dry-laid stone slope protection structure capable of effectively resisting both ice thrust and ice uplift forces is developed,and a comprehensive framework of design countermeasures for upstream dry-laid stone slope protection of earth dams in cold regions is established.The results demonstrate that the proposed measures can effectively mitigate frost damage to upstream dry-laid stone slope protection,thereby reducing the substantial labor,materials and financial resources required for frequent maintenance and reinforcement.The study provides valuable guidance and a reference for the design of earth dam slope protection in cold regions.
