Development On Virtual Simulation System Based On Multi-Supporting Building Moving Project

Building moving is a new engineering technology . The technology has many advantages, such as saving much money, material resources and time than other methods. It can also solve the conflict between city planning with the existing buildings of scientific value or useful, so the technology is developing quickly. However because building moving technology is a multi-disciplinary complex project, the theoretical research for the project is still not perfect and many problems need to be solved. Aiming at such problem, a simulation model for multi-supporting building moving project by sliding way is built and the effects caused by the boundary condition changes during the moving process is studied systemically in the paper. And then a computer aided design system of building moving engineering is also developed, which is significant to the project and can be a helpful tool of obtaining solutions. The research work is listed as following:(1) A method to pick up the parameter of building moving model is found out and the restraint method for the model is given by studying the characteristics of the building moving project. And then the parametric finite element model is built.(2) The comparison of characteristics for various underpinning structure is and the optimization design is done for the underpinning trusswork and the location of batter post. And then the characteristics of the two structural members and improvement aim are obtained. The conclusions of this paper is significant to building moving project.(3) The method of Birth and Death is used to stimulated the process of that when upper structure is separated from the basis during the building moving and the method of inertia relief is used to stimulated the process of jacking and horizontal moving, and then a computer aided design system based on VB for building moving project is developed. At he same time the simulation of digitalization and visualization on building moving project is realized.
