The Study For 3D Simulation And Analyse System Of Deep Pit Engineering

In recent years, Building-terra became intensity, more and more deep pitappereance.wich lead to new difficulty that traditional ways of designding pit andanalyse method do not meet with deep pit. Pit designing softwares are applied widely.However, for some reasons, there are not any all-purpose pit simulation and designingsoftware now.In this paper, according to investigate some pit simulation and designingsoftwares, the shortcoming of every sort software are appointed.then basede onsecondary exploitation techniques of AutoCAD and ANSYS, the 3D simulation andanalyse stytem of deep pit engineering is exploited. In which modeling isimplemented in entironment of AutoCAD.This system consists of P-CADTOANSYS module and Pit-Analyse module.P-CADTOANSYS module has friendly operation interface and modeling capcity.User can quickly establish the3D model of pit by drawing or read drawings exsited inAutoCAD.Meantime, user can mesh and evaluate attribute of elements inP-CADTOANSYS,which simply modeling procedure.Pit-Analyse module is exploited in ANSYS to in charge of analysed pit.In virtuof powerful calculation capability of ANSYS, this module can finish the direct andreverse analyse about pit and output the result with differently ways. Moreover, thismodule provided Chinese operation interface, which is easily to study and applied.Finally, this system is applied to directly analysed for pit engineering ofYOUYOU plaza and ChengHuangmiao in shanghai. Meantime, this system is adoptedto reverse analysed for pit engineering of ChengHuangmiao.According to datacomparing between calculation and practice, which indicates this system is valid.
