| 摘 要： | 紫坪铺面板坝经受了超设计标准的地震考验,经震后及时修复,目前其监测仪器运行正常,完好率达83%。震后大坝坝顶一次产生了81cm的明显震陷和超过30cm的水平位移,目前坝体变形已趋于稳定,但面板脱空及施工缝错抬现象明显。紫坪铺大坝具有较强的抗震能力,地震后坝体总体稳定,且堆石密度提高,有利于震后永久变形的减小。

| Abstract: | Zipingpu concrete face rockfill dam has withstood the test of ultra--seismic design stand- ards, after a timely post--earthquake restoration of its monitoring equipment is currently operating normally, good rate of 83%. Dam crest once after the earthquake produced an 81cm clear seismic suhsidence and more than 30cm of the horizontal displacement, the current deformation of the dam has stabilized, but the panel off the wrong space and the construction joints a noticeable lift. Zipingpu dam has a strong anti--seismic capacity of the overall stability of the dam after the earthquake, and the rock--fill density is conducive to the decrease of permanent deformation after the earthquake. |
