基于CATIA的地质BIM模型研发及应用

Research,Development and Application of Geological BIM Model Based on CATIA

CATIA凭借其优秀的曲面造型能力,广泛应用于市政行业,但其本身并不具备地质建模能力,相关应用也相对较少。现针对地质数据传递困难、地层建立过程复杂等问题,基于CATIA进行地质BIM模型建模方法研究。采用DACE工具箱的克里金模型拟合地质界面数据,结合CATIA软件优秀的曲面造型能力建立地形实体和地质界面,最终提供一种适用性高的地质BIM模型创建方法。结合3DE平台和CATIA的协同设计功能,保证了地质数据的有效传递,增强勘察专业与其他专业的工作协同,较好地解决了岩土相关的实际应用需求。

CATIA is widely used in municipal industry because of its excellent surface modeling ability.However,CATIA itself does not have the geological modeling ability,and its related applications are relatively few.Aiming at the problems of difficult geological data transmission and complex formation process,the geological BIM modeling method based on CATIA is studied.The Kriging model of DACE toolbox is used to fit the geological interface data.The excellent surface modeling ability of CATIA software is used to establish the terrain entity and geological interface.Finally,a highly applicable geological BIM model creation method is provided.Combined with the collaborative design functions of 3DE platform and CATIA,the effective transmission of geological data is ensured,the work cooperation between the survey specialty and other specialties is enhanced,and the practical application requirements related to rock and soil are well solved.
