【摘要】：為研究高聚物防滲墻土質堤壩地震加速度反應規(guī)律,采用El Centro波,在0.05 g、0.1 g、0.2 g和0.4 g工況下進行了高聚物防滲墻土質堤壩和傳統(tǒng)剛性防滲墻—混凝土防滲墻土質堤壩的離心機振動臺的對比試驗。試驗采用非等應力離心模型,利用加速度傳感器測量了壩體不同位置的加速度時程響應。結果表明:高聚物防滲墻土質堤壩峰值加速度隨輸入地震動增加而增加,隨壩高增加而增加,最大峰值加速度在壩頂上;高聚物防滲墻土質堤壩最大峰值加速度隨輸入地震動的增大呈線性增加趨勢,而最大峰值加速度放大系數(shù)隨輸入地震動增大而減小;從模型試驗的角度來看,在同等水平地震作用下,混凝土防滲墻土質堤壩抗地震加速度反應能力好于高聚物防滲墻土質堤壩,但在強震下混凝土防滲墻體發(fā)生了破壞,這一點可由附近土體加速度突增判斷。
[Abstract]:In order to study the seismic acceleration response law of polymer impervious wall earth dike, El Centro wave is used. Under the condition of 0.05 g / g 0.1g / g and 0.4 g / g, the centrifuge shaking table of soil dike with polymer impermeable wall and traditional rigid impermeable wall and concrete impermeable wall earth dyke is tested. The acceleration time history response at different positions of the dam was measured by using the non-equal stress centrifugal model and the acceleration sensor. The results show that the peak acceleration increases with the increase of input ground motion and increases with the increase of dam height, and the maximum peak acceleration is on the top of the dam. The maximum peak acceleration of polymer impermeable wall earth dike increases linearly with the increase of input ground motion, while the maximum peak acceleration magnifying factor decreases with the increase of input ground motion. Under the action of the same level earthquake, the seismic acceleration response ability of the concrete impervious wall earth dike is better than that of the polymer impervious wall earth dyke, but the concrete impervious wall is destroyed under the strong earthquake. This can be judged by the acceleration of nearby soil.
