ANSYS在整体式排水圆管分析中的应用

Application of ANSYS at Analyzing Whole Draining Round Pipe

基于ANSYS APDL参数化设计语言编写程序,利用程序对整体式排水圆管进行数值计算.模型中考虑了不同荷载的施工方法,并利用路径映射技术实现了各截面的内力输出,从而合理地揭示了在土压力、外水压力和自重的共同作用下整体式排水圆管的位移、应力和内力分布规律.最后通过工程实例,验证了程序的可靠性.

The program based on ANSYS APDL was compiled to calculate the parameters of whole draining round pipe numerically,the displacement,stress and internal force of the whole draining round pipe under the combined action of earth pressure,water pressure and gravity were analyzed.The loading methods were introduced briefly,and the technique of Path Mapping was used to compute the internal force.The program was applied to an engineering case,and the results are basically consistent with traditional elasticity center method of structure mechanics,so the program is reliable.
