【Abstract】 The research status of hydraulic fractures in concrete structures is reviewed.With regard to the existing problems in the research on hydraulic fractures in high concrete dams under multi-field coupling conditions,the worldwide results of hydraulic fractures in concrete structures are summarized from the perspectives of hydraulic fracturing theories,test techniques,numerical simulation methods,and crack propagation studies under different coupling conditions.Several prospects are proposed: test equipment and techniques for hydraulic fractures in high concrete dams under multi-field coupling conditions,crack propagation and coupling mechanisms for different coupling conditions,and numerical techniques considering arbitrary structural cracks.更多还原
