格宾石笼在潜坝坝面稳定性提升中的应用

Application of Gabion Mesh Cages in Stability Improvement of Submerged Dam Surface

摘要:

黄河下游河道宽浅散乱、河势演变频繁,潜坝是稳定河势、保障堤防安全的关键建筑物。传统浆砌石、混凝土刚性坝顶存在地基适应性差、透水性弱、施工复杂、后期维护成本高等问题。文章结合黄河下游防洪工程实践,提出一种以格宾石笼为核心的潜坝坝面稳定性提升施工工法,系统阐述工法特点与原理、施工工艺、质量安全控制要点。该工法具备柔性适应变形、透水消压、施工高效、生态友好、经济节约等显著优势,已在山东黄河多项工程中成功应用,效果显著。

Abstract:

The lower Yellow River features wide, shallow and scattered river channels with frequent river regime evolution. Submerged dams are key structures for stabilizing river regime and ensuring embankment safety. Traditional rigid dam surfaces built with stone masonry and concrete have disadvantages such as poor foundation adaptability, weak water permeability, complicated construction and high costs for post-maintenance. Combined with flood control engineering practices in the lower Yellow River, this paper proposes a construction method for improving submerged dam surface stability with gabion mesh cages as core components. Its technical features, working principle, construction procedures, quality-safety control points are illustrated. This method has prominent advantages including flexible deformation adaptability, water permeation and pressure dissipation, efficient construction, eco-friendliness and cost effectiveness. It has been successfully applied in multiple Yellow River projects in Shandong with sound performance.
