组合悬臂式挡土墙设计及有限元分析

Design and Finite Element Analysis of Combined Cantilever Retaining Wall

摘要:

受场地条件限制，珲春某文旅项目新建的挡土墙需要与新建的泄洪管廊组合设计成一体的组合悬臂式挡土墙。这种非常规挡土墙具备挡土和泄洪双重功能，已不是单一悬臂式结构模型，采用常规设计计算方法不适用，故采用有限元数值分析方法，计算该组合结构的整体稳定性，分析结构的受力和变形特征，并应用有限元计算结果进行钢筋混凝土设计。组合悬臂式挡土墙建成后的监测数据表明，该组合悬臂式支挡结构稳定，变形符合规范要求。

Abstract:

Due to the site limitations, the newly built retaining wall of a cultural tourism project in Hunchun needs to be combined with the newly built flood discharge utility tunnel to form a combined cantilever retaining wall. This unconventional retaining wall has dual functions of retaining soil and flood discharge, and is no longer a single cantilever structural model. The conventional design and calculation methods are not applicable. Therefore, the finite element numerical analysis method is used to calculate the overall stability of the combined structure, and analyze the stress and deformation characteristics of the structure. And the finite element calculation results are used for the reinforced concrete design. The monitoring data after the construction of the combined cantilever retaining wall shows that this combined cantilever retaining structure is stable and its deformation meets the requirements of the specifications.
