摘　　要：以汶川地震为主展开讨论,对汶川地震造成的简支梁桥灾害经验并进行分析。依据简支梁桥的结构特点,对简支梁桥的抗震进行震害调查分析、分析、防治措施以及抗震防灾技术材料等。对简支梁桥开展震害机理分析,从理论分析的角度揭示简支梁桥的震害本质,在此基础上提出简支梁桥在各个设计阶段应该具备的抗震设计理念,指出采用隔震控制技术是降低简支梁地震损伤的有效途径之一,并对该技术在国内外的应用和发展现状进行了全面阐述。This paper mainly discusses the Wenchuan earthquake,summarizes and analyzes the disaster experience of the simply supported beam bridge caused by the Wenchuan earthquake.According to the structural characteristics of the simply supported beam bridge,a series of research and discovery are carried out on the seismic damage investigation and analysis,the earthquake damage mechanism analysis,the prevention measures and the technical materials for earthquake resistance and disaster prevention.The seismic damage mechanism of simply supported beam bridge is analyzed,and the essence of seismic damage of simply supported beam bridge is revealed from the perspective of theoretical analysis,which also lays the foundation for the seismic research of simply supported beam bridge.On this basis,we put forward the seismic design concept of simply supported beam bridge in various design stages,and pointed out that the use of seismic isolation control technology is one of the effective ways to reduce the seismic damage of simply supported beam,and comprehensively described the application and development status of this technology at home and abroad.
