| 摘 要： | 冶勒大坝为沥青混凝土心墙堆石坝,最大坝高124.5 m,坝基地质条件极其复杂.该坝址距"5.12"坟川大地震震中约258 km,地震发生时坝区震感强烈.从渗流量及渗流场变化、坝基覆盖层液化和防渗墙地质雷达检测结果等3个方面分析评价了汶川地震对冶勒大坝右岸抗渗稳定性的影响.结果表明:汶川地震对冶勒大坝右岸局部地层确有轻微影响,但防渗墙未出现横向贯穿性裂缝;坝基覆盖层在地震主震作用下不会发生液化;右岸整体抗渗稳定性并未受到实质性影响.

| Abstract: | The Yele rockfill dam with an asphalt concrete core wall has a maximum height of 124.5 m and the geological condition of its foundation is extremely complex.The dam site is about 258 km to the epicenter of Wenchuan Earthquake and has a strong shock during earthquake.The impermeability stability of the right bank of dam was analyzed from the changes of seepage quantity and flow field,the liquefaction of overburden on dam foundation and the testing results of Ground Penetrating Radar for cut-off wall.The resu... |
