摘　　要：小浪底工程进水口引渠导墙跨越F236、F238两大断层及其间的小断层所在的冲沟，其作用是同进水塔建筑物协调运用，引导水沙在进水塔前缘形成道时针大回流，产生大的冲刷漏斗，以有效地防止进水口被泥沙淤堵和顺利地排污排漂。基础处理采用了混凝土塞与固结灌浆相结合的方法，并针对不同区段的地基优劣，采用了轻型混凝土结构、重力式挡土墙和混凝土基座堆石体等不同的结构型式，以适应复杂的地质条件。Aimed at effective protection of clog at intake by sediment and smooth transportation of trash and drift boulder through combining operation with intake tower constrllctions to guide sediment loaded flow to form anti-clockwise back flow in large scale in front of the intake tower and consequently form large scouring funnel, the guide wall of water approach channel at intake of Xiaolangdi project stride across gullies with two big faults, F236 and F238, and other small faults. The way of combining concrete clogging and grouting consolidation was applied to base treatment, in order to fit complicated geological conditions, light concrete structure, gravity retaining wall, concrete stone pile base and other structures have been applied according to poor and strong bases in different sites.
