【摘要】 分析了东江水电站坝址区主要断层活动性近１０ａ的原位监测成果，检验了坝址区Ｆ３断层工程处理方案理论验算的有效性和工程处理效果的可靠性。断层活动性原位长期连续监测，是类似工程条件下保障大坝安全的有效措施之一。更多还原

【Abstract】 The in-situ observation result about 10 years of main fault activity in Dongjiang dam area proves the validity of computation check about engineering program and the reliability of treatment effect concerning fault F3. Long-term continuous in-situ observation of fault activity is one of the efficient measures to ensure dam safety under the similar engineering condition.更多还原
