谈几种常用本构模型在强夯沉降计算中的应用

On application of some common constitutive models in calculation of dynamic compactness and settlement

以厦门航空港区港联动区与货运配套区围填工程强夯地基处理为例,结合分层总和法的地基沉降量计算理论对地基沉降量计算进行应用,并采用线弹性模型、非线性弹性模型、弹塑性模型三种类型的四个模型进行强夯处理后场地工后沉降二维有限元分析,对各不同模型进行了分析对比,以期为类似地基处理工程研究、设计提供借鉴。

Taking the dynamic compactness of foundation in the surrounding and filling project between the region-harbor synergy of Xiamen Airport as the example, the paper combines the settlement calculation theory of the layer-wise summation method to apply the foundation settlement calculation, adopts the linear elastic model, the non-linear elastic model, the elastoplastic model to have the settlement two-dimension finite elementary analysis of the field after the dynamic compactness, and undertakes the analysis and comparison of the various models, so as to provide the reference for the research and design of the similar foundation treatment projects.
