摘要
流溪河拱坝运行４０余年，存在向上游方向的不可逆位移。经过研究，证实不可逆位移数值不大，且近年已有所缓解，目前对大坝安全未构成威协。其原因有多种假设，最大的可能是由于拱坝的结构与其工况所引起。该坝这种不可逆的位移，近十年还存在，必须引起注意。
The Liuxihe arch dam has worked for ever 40 years. Irreversible upstream displacement has been observed. Research verifies that, the irreversible displacement is limited and it has been slowing down in recent years, not threatening the dam safety. The problem has several explanations and the most probable is that, it stems from structure and performce of the arch dam. The irreversible displacement of the dam has exhibited in the past ten years and close attention must be paid to it.
