大型有限元软件ANSYS在堆山工程中的应用

建筑垃圾堆山造景是生态城市建设中的一个新课题,是有效处理及利用建筑垃圾的新方法,然而地基基础沉降和山体稳定性是建筑垃圾堆山造景中山体设计的关键.现利用大型有限元通用软件ANSYS对山体在自重载荷作用下的沉降和稳定性进行实体模型仿真计算,并与工程常用简化计算进行比较,两者结果基本一致.并在有限元计算中,利用ANSYS有限元软件中的参数化设计语言(APDL)编制了山体塑性判别程序,进而对山体堆填过程的沉降和稳定性有一个整体的了解,这对山体的施工有巨大的指导意义.这将为类似工程山体设计和施工控制提供有效依据.

Application of large-scale software ANSYS to piling mountain project

It is a new content to pile mountain and make man-made scene with construction waste in the ecological city construction filed, and it is a novel method of dealing and applying with construction waste. However, ground settlement and mountain stability are keys in mountain design of piled mountain and make man-made scene with construction waste. Ground settlement and mountain stability are computed on the basis of solid imitate model, which is loaded dead load, with FEM software /ANSYS. The result is compared with other result that is computed with common simplified formula. The results are coincident In FE computing, the mountain plastic program is used,which is compiled with APDL, therefore, the condition of ground settlement and mountain stability through construction are captured. It is great significance for construction. It will make a reference and rule for other projects.
