坝体结构稳定和坝基防渗是决定工程安全和预期效益的关键因素。柏岭寺水库水利枢纽工程设计方案，大坝采用碾压混凝土重力坝，大坝基础开挖后，坝基持力层由砾岩变为砂岩。现有的混凝土重力坝大多数建在硬岩，软基上建坝的较少，通过调整坝体边坡，改变局部尺寸和坝基灌浆方案的措施，解决了软弱基岩上坝体稳定，坝基渗漏等问题，可为类似工程设计方案的选定提供一定的参考价值。
壩體結構穩定和壩基防滲是決定工程安全和預期效益的關鍵因素。柏嶺寺水庫水利樞紐工程設計方案，大壩採用碾壓混凝土重力壩，大壩基礎開挖後，壩基持力層由礫巖變為砂巖。現有的混凝土重力壩大多數建在硬巖，軟基上建壩的較少，通過調整壩體邊坡，改變跼部呎吋和壩基灌漿方案的措施，解決瞭軟弱基巖上壩體穩定，壩基滲漏等問題，可為類似工程設計方案的選定提供一定的參攷價值。

The stability of dam structure and the seepage prevention of the dam foundation are the key factors that affect the safety of the construction and the achievement of the expected benefit .The design scheme of a hydro - junction pro-ject ,Bailingsi reservoir was introduced in this paper .Its dam is roller-compacted gravity dam .After the excavation of the dam foundation ,the supporting layer of the foundation transferred from the conglomerate layer to the sandstone layer . However ,existing concrete gravity dams were mostly built on hard rocks ,rarely on soft rocks .Through the adjustment of the slope ,partial specification and the grouting measures of the dam foundation ,the stability and seepage problems of the Bailingsi reservoir dam which was built on the soft rock foundation were solved .This study can provide some references for the design of similar engineering projects .
