Paper Abstract

By use of 3D dynamic visual simulation technology based on GIS, this paper puts forward a suit of construction system of 3D visual digital modal and construction process simulation methods for pit foundation. Graphical modeling and dynamic simulation of the entire construction process visualization was realized. At first, the 3D geologic strata model is realized according to pre-results of our research group, the 3D visual digital model construction method and corresponding standard database establishment are discussed, and then according to the relational database, the whole up-down construction method of pit foundation construction process dynamic simulation path is set up. The graphical modeling facilitates the establishment of simulation model by combining graphic model elements based on hierarchical modular modeling theory. The entire process uses discrete event system simulation basic concept, adjusts to use relational database, and carries out construction model combination. Combining the whole and detail simulation states, the paper carries out the entire dynamic construction progress simulation, and at last develops a large 3D visual simulation system of pit foundation based on the World Expo 500kV transformer substation pit foundation of Shanghai World Exhibition.
