An extensive investigation into the responses of a fresh concrete pipe pile induced by the adjacent penetration of a pipe pile casing into clay, undertaken through large-deformation finite-element analysis, is described in this paper. The numerical model was validated using field monitoring and centrifuge test data in terms of penetration resistance and soil deformation, and good agreement was obtained. An extensive parametric study was conducted encompassing the practical range of relevant parameters, including penetration depth, soil properties, the distance between the casing and the fresh concrete pile, casing diameter, soil layer thickness and roughness. A formula for estimating the maximum lateral deformation of a fresh concrete pile was developed to provide guidance for practical pipe pile design.

管桩在粘土中的渗透对新拌混凝土桩的响应

通过大变形有限元分析，对新的混凝土管桩的响应进行了广泛的研究，该研究由管桩壳体的相邻渗透引起的黏土引起。通过现场监测和离心试验数据验证了数值模型的抗渗性和土壤变形，并取得了良好的一致性。进行了广泛的参数研究，涵盖了相关参数的实际范围，包括穿透深度，土壤特性，套管与新鲜混凝土桩之间的距离，套管直径，土壤层厚度和粗糙度。提出了估算新拌混凝土桩最大横向变形的公式，为实际的管桩设计提供指导。
