摘要
珠海横琴桥址软基较厚,淤泥现流塑态,桥梁桩基施工过程中存在缩颈等不良现象。为解决桩基高质量成桩、提高桩基耐久性,以及降低造价三大因素出发,提出采用双钢护筒进行施工。
The soft subgrade of Hengqin Birdge in Zhuhai is thicker, and its mud flow is in plastic state. The bad phenomenon of neck down exists in the construction of bridge pile subgrade. Starting from three factors of solving the finished high-quality pile of pile subgrade, improving the durability of pile subgrade and reducing the construction cost, the double-steel pile casing is proposed for construction.
