Anti-explosion tough face plate structure of rock-fill dam and construction method of anti-explosion tough face plate structure
The rock-fill dam anti-knock tough panel structure comprises an anti-knock tough panel and a transition cushion layer which are arranged on the upstream side from outside to inside, a rock-fill body is arranged on the downstream side of the transition cushion layer, a wave wall is arranged at the top end of the anti-knock tough panel, a toe board is arranged at the bottom end of the anti-knock tough panel, and the anti-knock tough panel and the transition cushion layer are arranged on the downstream side of the transition cushion layer. The portion, close to the transition cushion layer, of the anti-knock tough panel is a common concrete layer, the portion, away from the transition cushion layer, of the anti-knock tough panel is a fiber-reinforced high-performance concrete layer, and the portion between the common concrete layer and the fiber-reinforced high-performance concrete layer is filled with wave-absorbing and energy-dissipating materials. On one hand, the anti-cracking and anti-seepage capacities of the panel are improved; and on the other hand, explosion impact is resisted and absorbed through the functional gradient panel, and the anti-explosion capacity of the panel is improved. Meanwhile, all the components of the panel can be partially or integrally replaced according to the damage condition after explosion, rapid repairing of the panel structure is achieved, and the design target of the anti-explosion toughness of the concrete faced rockfill dam is achieved.
本发明提出了一种堆石坝抗爆韧性面板结构及施工方法，包括在上游侧由外到内设置的抗爆韧性面板和过渡垫层，在所述过渡垫层的下游侧设置有堆石体，所述抗爆韧性面板的顶端设置有防浪墙，抗爆韧性面板的底端设置有趾板，所述抗爆韧性面板靠近过渡垫层为普通混凝土层，远离过渡垫层为纤维增强高性能混凝土层，所述普通混凝土层和纤维增强高性能混凝土层之间填充有吸波消能材料。本发明一方面，提高了面板的抗裂和抗渗能力；另一方面，通过功能梯度面板抵抗、吸收爆炸冲击，提高面板抗爆能力。同时，该面板各组成部分可根据爆后损伤情况进行局部或整体替换，实现面板结构的快速修复，达到面板堆石坝抗爆韧性设计目标。
