摘要
恰甫其海工程坝基处理过程中发现F34断层和"葫芦状"冲刷坑有形成渗漏通道的危险,故对该不良地质条件进行了工程处理。对F34断层采取浇筑混凝土塞、增加灌浆数目以及对下游做反滤覆盖等工程处理措施;对冲刷坑具体措施为浇筑混凝土塞、增加固结灌浆的数量及深度等工程措施。
Dangers of fault F34 and leakage channel formed by ＇gourd-like＇ scour pit are discovered in Qiafuqihai project dam foundation treatment process. The adverse geological conditions are treated. Concrete plug pouring, mortar filling increase, downstream reverse filtration coverage and other project treatment measures are adopted on fault F34. Concrete plug pouring, increase of consolidation grouting and depth, and other project measures are concretely adopted on scour pit.
