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.
本发明公开了一种基于有限元模型分析的基坑开挖变形研究方法，涉及基坑施工领域，包括以下步骤：S1、选择土体本构模型；S2、选取土层参数，将各项土体物理力学性质参数带入到S1中的土体本构模型；S3、支护桩等效计算，将基坑四周支护桩等效简化为板单元；S4、建立三维有限元模型，并对其进行网格划分；S5、对三维有限元模型分析、汇总并得出结论。本发明通过对基坑开挖过程关键步骤的模拟分析，研究基坑分区域开挖、分层开挖和分时开挖对基坑变形和基坑支护结构的受力情况的影响，验证基坑开挖工程的合理性，可以有效指导施工现场和控制基坑变形，对具有类似较大区域深基坑开挖的工程，具有很好的推广性。
