| 摘 要： | 根据抗弯刚度等效原则,推导出素混凝土-钢筋混凝土钻孔咬合灌注桩围护结构的等效本构关系.在此基础上,将钻孔咬合灌注桩围护结构等效为地下连续墙.简化模型的有效性通过ANSYS数值模拟方法进行了验证.简化计算模型的建立,方便了利用有限元方法对深基坑开挖过程中支护结构对土体变形影响的模拟分析.

| Abstract: | According to the equivalence principle of flexural rigidity,this paper presents the equivalent constitutive relation of enclosure structure for bored occluded piles composed of plain concrete and reinforced concrete.Supposing the enclosure structure of bored occluded piles could be the equivalent of the underground continuous wallt,he validity of the simplified model is verified by ANSYS numerical simulation method.The simplified model facilitates the simu-lation analysis of the impact of enclosure structur... |
