摘　　要：云州水库运行30多年来,虽经过续建和加固,但未从根本上解决水库主要建筑物自身安全和对下游地区的防洪安全。水库副坝区渗漏严重,高水位运行时存在渗流稳定问题。经过论证分析,副坝区采用混凝土防渗墙垂直防渗,防渗墙截渗总面积3万m2。防渗墙工程已建成1a多,截断了副坝及库岸区强渗漏带,减小了库区渗漏,消除了安全隐患。After continued construction and reinforcement for the past three decades, the problem of the safety of the ma- jor structures and the flood control in the downstream in the Yunzhou Dam is still not solved. Becaues of the serious seep- age auxiliary dam, the seepage problem and stability of dam have existed when the reservoir in the high water mark move- ment. After analysis and discussion, the vertical anti-seepage of concrete anti-seepage wall with a total area of about 30 thousand m2 is introduced in the auxiliary dam. Since its commission for one year, the seepageinterception has been made in the strong seepage zone of the auxihary dam and dam region, the potential safety hazard has been eliminated, the seep- age in dam region has been reduced.
