失稳多台阶自嵌块加筋挡土墙的联合加固技术

Combined Reinforcement Technology of Unstable Multi-step Self Embedded Block Reinforced Retaining Wall

某项目由于自嵌块加筋挡土墙本身固有的缺陷和施工质量问题,导致出现多台阶自嵌块加筋挡土墙变形失稳现象。通过对该工程实例失稳原因的进行分析,提出“重力式挡土墙+钢筋混凝土面板+预应力锚索+格构梁+注浆”的联合加固技术处理方案。方案实施后,经过一个水文年的监测结果表明加固工程取得预期效果。

Due to the inherent defects and construction quality problems of self inlaid reinforced retaining wall in a project,the multi-step self inlaid reinforced retaining wall is deformed and unstable.Through the analysis of the instability causes of the project example,the combined reinforcement technology scheme of"gravity retaining wall+reinforced concrete panel+prestressed anchor cable+lattice beam+grouting"is put forward.After the implementation of the scheme,the monitoring results of one hydrological year show that the reinforcement project has achieved the expected effect.
