强地震下过渡段路基与重力式桥台破坏特性
Damage characteristics of transition section roadbed and gravity abutment under strong earthquake
【摘要】 以某简支梁桥的重力式桥台为分析对象,建立了路基与桥台的三维动力分析模型,通过地震荷载输入研究,分析路基与桥台的破坏特性,最后得出相关结果,从而对挡土墙等的破坏机制有更深了解,更好保证路基、桥台的安全。
【Abstract】 Taking gravity abutment of a simply supported beam abutment as the analysis object,this paper established three-dimensional dynamic analysis model of subgrade and abutment,through the research on seismic load input,analysed the damage characteristics of subgrade and abutment,lastly gained the relevant results,so as to had a deeper understanding to the failure mechanism of retaining wall and other aspects,better guaranteed the safety of subgrade and abutment.
