摘　　要：介绍了一个简化的水槽地基模型及其在通用有限元软件MARC的运用和实现。充分运用静力学和结构动力学理论分析了水槽在受自重和水压力作用下及其三向地震荷载作用下的应力和位移情况,又通过比较在静荷载叠加规范谱和静力两种情况下应力位移的变化过程,并通过一系列的图表给出了相应的结果。A simple gutter-ground model and its application and realization in the finite element software MARC are intro- duced. Adequately using the static theory and structural dynamic theory, the gutter＇ s stress and displacement in all directions suffered by the gravity and the hydraulic force or the seismic force in three directions are analyzed. And through comparing the two situations of the static load superimpositions with the canonical spectrum and the static loads with no canonical spectrum, the changing course of the stress and displacement is analyzed. At last, the corresponding results are obtained by a series of tables.
