对于有着地震威胁的景观闸, 应该进行抗震分析, 有限单元法作为目前工程领域中的一种重要数值模拟方法, 已逐渐作为抗震分析的重要手段。以上海某景观闸工程为例, 采用反应谱法模拟地震响应, 附加质量法模拟地震动 水压力, 通过大型有限元软件ABAQUS 进行有限元数值计算, 分析该水闸闸室段的应力与位移, 验证设计方案的 有效性。

Seismic ana lysis should be car ried out fo r the landscape sluice which has the risk o f eart hquake. As an important nu2 mer ical simulation method used in the engineer ing field, finite element method has been widely used for seismic analy sis. In t his paper , a landscape sluice in Shang hai w as t aken as an ex ample. The respo nse spectr um metho d w as adopted to simulate the seis2 mic r espo nse, and the additio nal mass method w as adopted to simulate the ea rthquake dynamic w ater pr essure. Finite element so ftwa re ABAQUS was used to perfo rm the numer ical calculatio ns, to ana lyze the str ess and displacement o f the sluice cham2 ber, and to v erify the validity.
