摘　　要：高土石坝初蓄期对库水位抬升速率有严格的限制。通过对某砾石土心墙堆石坝初蓄期库水位变化与坝体变形的分析研究,发现库水位抬升速率过快易导致坝体产生较大变形,严重时可能对坝体防渗结构产生破坏。因此,心墙土石坝在初蓄期严格控制库水位抬升过程,加强坝体变形监测对确保大坝的安全具有重要意义。There is a strict restriction on the rising rate of reservoir level during the initial impoundment period of high earth-rock dams.Through analysis and research on the change of reservoir level and the dam deformation during the initial impoundment period,it is found that high rising rate of reservoir level is prone to cause large deformation,and in serious cases,it may damage the seepage prevention structure.Therefore,it is of significance to strictly control the rising process of reservoir level and strengthen the dam deformation monitoring in the initial impoundment period to ensure the dam safety.
