Traditional approachof 2D design and construction management no longermeets the increasingly complex needs of the pit engineering, while the emergence of BIM technology provides technical support to address these issues, and also provides a new way to verify the safety of the foundation pit support structure whencombined with the finite element analysis.This paper presents a foundation pit engineering example that the BIM technology is introduced and the BIM foundation pit support model is established by CATIA. Also, Navisworks is applied for foundation pit construction simulation. This paper analyzesseveral methods for the combination of CATIA and finite element, and applies ABAQUS, a finite element analysis software, to verify the stability of foundation pit support structure.Practical engineering application shows that theBIM technology combined with the finite element analysis, is of great application valuein practical foundation pit engineering.
