中文摘要:
      根据巢湖软土工程地质勘查报告,建立了某基坑双排桩支护结构体系二维有限元数值计算模型。在合理选取土的本构模型参数的基础上,进行了双排桩支护结构的内力和变形特性数值模拟分析。计算结果显现了双排桩支护结构最大弯矩,基坑最大侧移变形,基坑地表最大沉降,为巢湖软土基坑双排桩支护结构设计的优化提供了参考依据。
英文摘要:
      According to engineering geology exploration report of ChaoHu soft soil, the two-dimensional finite element numerical calculation model of foundation pit retaining structure with double-row piles is established. Based on the reasonable selection of soil constitutive models and their corresponding parameters, numerical analysis are carried out to analyze the mechanical properties of internal force and lateral displacement of retaining structure. The maximum bending moment, maximum lateral deformation and maximum ground settlement of retaining structure are obtained finally. The results provide theoretical basis for the design optimization.
