  中,再与筏板根本的无网格法耦合起来进行计较阐发,从而使该配合感化新方式 能对工程现实中高层建筑的分歧上部布局(如框架-剪力墙布局、筒体布局、框架- 筒体布局)与筏板根本、地基配合感化进行计较阐发,通过算例阐发及与贸易无限 元软件ANSYS 计较成果的比力,表白该方式是无效可行的。 ⑥ 针对上述各类计较理论及阐发内容,自行编制了响应的面向对象计较法式 PIASRFS-2007 ,法式用 C++言语在 VC++平台中编制,采用该法式能够采用无网 格法对筏板根本进行计较阐发,并能对分歧平面外形、分歧厚度的筏板根本与 Winkler 、双参数弹性地基及高层建筑的分歧上部布局进行三者的配合感化计较分 析,该法式为高层建筑筏板根本工程实践供给了一种新型无效的阐发手段。通过 法式计较能够得出工程上关怀的考虑与上部布局、地基配合感化的筏板根本的挠 度(地基的沉降) 、筏板根本内力、上部布局(包罗上部各层梁、柱、剪力墙) 内力等 布局设想所需的目标,可为相关的具体工程实践供给指点及根据。 环节词:无网格法,无单位 Galerkin 法,重构核粒子法,天然单位法,Kirchhoff 薄板,Mindlin 中厚板,Winkler 地基模子,双参数地基模子,筏板根本, 上部布局与地基根本配合感化,框架布局,框架剪力墙布局,数值阐发 II ABSTRACT Meshless method is a new numerical computation method that is developed rapidly in recent years. Without element mesh and based on the dispersed nodes to form approximate interpolative function dynamically, meshless method has distinct difference with traditional finite element method. Meshless method conquers the problems caused by mesh generation, mesh aberration and mesh move. With provides a new effective means to engineering problem, meshless method obtain highly recognition in international compute mechanics domain and engineering field. Based on the developing trends of the meshless numerical analytical method and the interaction research of raft foundation with soil and superstructure, meshless computation methods for elastic foundation plate are researched by using the relative works in existence for reference adequately. And this elastic foundation plate meshless method computation theory is used in the interaction numerical analysis of raft fo
