南丹县天生桥水库双铰拱坝防渗加固设计

Anti-seepage Reinforcement Design for Double-hinged Arch Dam of Tianshengqiao Reservoir in Nandan County

南丹县天生桥水库除险加固工程由于大坝为浆砌石双铰拱坝,为增加坝体防渗作用,且不改变双铰拱坝受力结构,采用碳纤维布防渗加固补强,能够改善双铰拱坝的结构强度和韧性,从而提高双铰拱坝的整体性、耐久性、抗渗性和使用寿命。

The sick stone masonry double-hinged arch dam of Tianshengqiao reservoir in Nandan County is rein- forced by carbon fiber sheets as so to increase the anti-seepage effect of dam body under the premise of not changing the forced structure of the dam, which improves not only the structural strength and toughness of the dam, but also the integrity, durability, anti-permeability and service life of the dam.
