基于锚栓联接的装配式挡墙设计与施工工艺研究

Research on Design and Construction Technology of Assembly Retaining Wall Based on Anchor Bolt Connection

摘要: 联接节点是装配式挡土墙设计的关键。在对比分析不同联接节点优缺点的基础上，提出了一种预留锚栓联接的装配式挡土墙。挡墙单元由预制立板和底板组成，在底板上预留锚栓，在立板底部预留锚栓孔，通过座浆消除立板与底板间间隙，通过锚栓、螺母、垫片将立板和底板联接在一起。给出了挡土墙的设计计算方法与施工工艺，并进行了工程应用，可为类似工程的设计与建造提供参考。

Abstract: The connection node is the key to the design of the assembly retaining wall. On the basis of com-parison and analysis of the advantages and disadvantages of different joints, an assembly retaining wall with anchor bolt connection is proposed. The wall unit consists of a prefabricated vertical plate and a prefabricated bottom plate, and several anchor bolts are reserved on the floor, and the same number of anchor holes is reserved at the bottom of the vertical plate, removing the gap between the vertical plate and the floor by the slurry technology, and the vertical plate and bottom plate are connected by bolts, nuts, and gaskets. The design calculation method and construction technology of the wall are given, and the engineering application is carried out, which can provide reference for the design and construction of similar projects.
