桥巩水电站船闸引航道岩质边坡支护研究

Rock slope supports research for approach channels of shiplock at Qiaogong Hydropower Station

桥巩水电站船闸上下游引航道岩质边坡地质条件复杂,开挖后暴露出来的岩体比较破碎,局部岩体溶蚀裂隙、溶沟和溶槽发育,存在隐患,为保证岩质边坡的稳定要求,提出了几种支护方案,通过对每种方案的优劣比较,提出了最优的支护措施。

At the rock slope by the upstream and downstream approach channels of the shiplock at Qiaogong Hydropower Station, geological conditions are complicated. The rockrnass exposed after excavation behaves fairly crushed, with solution fissure, corroded gully and solution groove developed locally, which endanger the stability of rock slope. To solve this problem, the optimum support scheme was determined after a comparison among several schemes.
