Abstract: In the early storage period, the control of reservoir rise rate is an important issue for deformation and stability of the core wall. By analysis of the monitoring data on deformation and seepage in different parts of the core wall, conclusion was obtained that the fast rise of reservoir level would cause larger deformation of the core wall, and the deformation of core wall would reduce the effective stress of soil. With the effect of reservoir water, seepage may occur because of hydraulic fracturing.

Key words: rockfill dam, core wall, deformation, seepage

摘要： 高土石坝初蓄期控制库水位抬升速率是确保坝体心墙变形稳定的重要措施，通过对大坝心墙不同部位变形和渗流的监测数据分析，认为库水位过快的抬升速率将导致坝体心墙变形过大，过大的心墙变形会降低土体内的有效应力，在库水位作用下易产生水力劈裂，造成坝体心墙局部渗漏。
