摘要
病险水利工程的研究与治理是我国水利部门的一项急迫工作。本文介绍了官厅水库存在的坝基可液化砂层、闸基软弱夹层、两岸绕坝渗漏、右坝肩埋藏谷内堆积物潜在渗透变形等主要地质灾害问题及其治理措施,并深入分析讨论了溢洪道边坡稳定问题。
It is urgent for the hydro-engineering Dep. to study and control the diseased and dan-gerrous hydro-engineering. The main environmental geological problems in Guanting reservoir have been present in this paper. Thoes are: the liquefieable sand stratum under dam foundation, the weak intercalations under gate base, the leakage around the dam abutment, the seepage deformation of deposits in buried ancient channel near right risht abutment of the dam. The control methods of these hazards have been also introduced. At last, the authors have discussed the stability of left slope on tail part of spillway by means of mechanical analysing and calculating.
