摘要：

冶勒大坝为沥青混凝土心墙堆石坝，最大坝高124.5 m，坝址地震烈度高、地质条件复杂。该坝址距离“5.12”汶川大地震震中258 km，地震发生时坝区有强烈震感。坝上布置了由9台强震仪组成的强震监测台阵及埋设有较完整的大坝安全监测仪器，在此次汶川地震中获得了较完整的地震记录和其他监测资料。通过对强震监测资料及地震前后大坝变形、应力、应变及渗流渗压等方面的分析，考察汶川大地震对冶勒大坝工作性态产生的影响。分析结果表明，地震对大坝整体的应力、应变、渗流渗压并未造成明显的不利影响，但对大坝局部结构产生了一些不利的影响。总体而言，整个大坝在遭遇Ms8.0级大地震之后，外观无异常现象，总体运行性态基本稳定。

Abstract:

Yele Dam is a rockfill dam with an asphaltic concrete core wall. The maximum dam height is 124.5 m; and the geological conditions of the foundation are quite complex with a high degree of seismic intensity. The dam area was shocked strongly at an epicentral distance of about 258 km. There are 9 accelerographs and some other monitoring instruments on the dam. And they obtained comparatively complete records of the earthquake and other monitoring data during Wenchuan Earthquake. The effects of Wenchuan Earthquake on Yele Dam were studied based on the earthquake records and the analysis of the deformation, stress and strain, as well as seepage and osmotic pressure. Based on these analysis there had no significant adverse effects on the dam, but it still had some disadvantage effects on the partial structure of the dam. It was concluded that there was no exceptional appearance and the dam remained in normal working state after the Ms8.0 earthquake.

Key words: Wenchuan earthquake, rockfill dam, asphaltic concrete core, strong earthquake records, monitoring data
