【摘要】 基于以不连续的时间点和空间点近似描述大圆筒结构连续振动下沉过程的方法 ,利用ANSYS-LSDYNA瞬态有限元计算软件,建立土体的粘弹塑性弹簧模型来模拟大圆筒结构的振动下沉过程,以获得大圆筒结构下沉过程筒体各点的应力极值,并与现场试验的数据进行对比,为大圆筒结构的设计和施工提供参考。更多还原

【Abstract】 The discontinuous space points and time points are applied for plotting the continuous vibratingsubsidence process of large-diameter cylinder.A soil’s viscoelastic plasticity spring model is built to simulate the vibrating-subsidence of the large-diameter cylinder with the transient finite element software ANSYS-LSDYNA.Then the maximum stresses at different points of the large-diameter cylinder are compared with the test results in the field,which will provide references for the design and construction of large-diameter cylinder.更多还原
