The Application of BIM Building Model in the Construction Process of Building Engineering
The excavation depth of the ultra-deep foundation pit of a shield well reaches 36.8 m,which puts forward high requirements for the safety of the envelope structure.Research process using BIM geotechnical engineering related analysis software to establish the finite element model of foundation pit and envelope structure,the excavation process is divided into 11 conditions,when the excavation to the base design ele-vation,simulate the horizontal displacement of underground continuous wall depth and foundation pit surface settlement,found that the support-ing system overall safety is good,and the excavation method is reasonable.Using this model to optimize the design parameters of the envelope structure,the thickness of the underground continuous wall can be reduced from 1.0 m of the original scheme to 0.8 m,or the coagulation strength level can be reduced from C35 to C30.The optimization measures are conducive to reducing the project cost.
