垫层料碾压对挤压墙变位的影响

Study on Effect of Cushion Rolling on Extrusion Wall Deformation

挤压墙技术是面板堆石坝施工中的新技术。针对垫层料碾压所引起的挤压墙变形进行了非线性仿真分析研究。研究结果表明 ,由垫层料侧压力所引起的挤压墙水平位移很小 。

Extrusion-pattern wall is a new kind of technique in construction of faceplate rock-fill dam. Aiming at the problem of extrusion-pattern wall deformation brought by cushion rolling, non-linear emulation analysis and researches are conducted. The results show that the horizontal displacement of extrusion wall caused by side-pressure of cushion rolling is very slight, and the upper-reach slope gradient caused by cushion rolling can satisfy design and faceplate construction requirements.
