临时柱板式锚定板挡土墙在旧路改造工程中的应用

Application of Anchor Plate Retaining Wall with Temporary Pillar to Old Highway Reconstruction Engineering

结合国道301旧路改造工程中临时柱板式锚定板挡土墙的设计和施工应用,着重讨论了临时柱板式锚定板挡土墙的墙后土压力、板后土压力、锚定板抗拔能力和结构稳定性分析,介绍了构件设计和施工工艺。实践证明这是一种经济适用的填方支护方法。

The soil pressure behind wall, soil pressure behind support plate, capability of anchor plates as well as the stability analysis of the structure of anchor plat e retaining wall with temporary pillar were discussed combined with the design a nd construction of anchor plate retaining wall with temporary pillar in the reco nstruction engineering of national highway 301. The structure design and constru ction methods were introduced. It was verified through practice that this constr uction technology was economical and applicable.
