Oversized aluminum veneer suspended ceiling metal pendant and flatness control method
The invention discloses a foundation pit excavation deformation research method based on finite element model analysis, and relates to the field of foundation pit construction, and the foundation pit excavation deformation research method comprises the following steps: S1, selecting a soil constitutive model; s2, soil layer parameters are selected, and various physical and mechanical property parameters of the soil body are substituted into the soil body constitutive model in the S1; s3, equivalently calculating the support piles, and equivalently simplifying the support piles around the foundation pit into plate units; s4, establishing a three-dimensional finite element model, and performing grid division on the three-dimensional finite element model; and S5, analyzing and summarizing the three-dimensional finite element model and obtaining a conclusion. According to the method, through simulation analysis of key steps in the foundation pit excavation process, influences of regional excavation, layered excavation and time-sharing excavation of the foundation pit on foundation pit deformation and stress conditions of a foundation pit supporting structure are researched, reasonability of foundation pit excavation engineering is verified, a construction site can be effectively guided, foundation pit deformation can be effectively controlled, and the foundation pit excavation efficiency is improved. And the method has good generalization performance for projects with similar large-area deep foundation pit excavation.
