水利枢纽工程船闸闸首三维有限元计算分析OA

This study investigates the lock head of a major hydraulic hub project characterized by strongly developed karst features and densely distributed faults,which compromise the integrity and mechanical properties of the surrounding rock mass.Such geological conditions impose significant challenges to the stability and safety of the lock head structure.A three-dimensional finite element model was established to analyze the deformation response and stress distribution of the lock head side pier under karst-influenced foundations.The results provide a technical basis for determining appropriate foundation treatment measures.Furthermore,the deformation and stress behavior of the lock head under high hydraulic head and large thrust forces were evaluated,offering essential guidance for selecting a reasonable structural form.The findings serve as a reference for the design and safety assessment of similar lock head structures in hydraulic hub projects.
