摘要
"5.12"汶川地震中水坝损毁严重,造成了巨大的经济损失。震后对69座溃坝险情和310座高危险情水库水坝进行了系统的调查,典型震害现象包括坝体裂缝、塌陷、滑坡、渗漏、启闭设施损坏和其他附属设施的损毁等。文中给出了不同烈度区的水坝震害分布,并对地震中水坝的震害现象做了初步总结和分析。
Wenchuan Earthquake caused serious damage quake, a systematic investigation was carried out for 69 to the dams and great economic losses. After the earthdams which would collapse and 310 dams which were at high risk. The typical earthquake damage to dams included crack , subsidence of dam, slip of dam slope, leakage of dam body and destruction of release works and other accessory facilities. In this paper, the distribution of earthquake-induced dam mary were made for damage is shown in the zones with different seismic intensities. Finally, the analysis and sumthe dam damage in the earthquake.
