摘要
以黄岛地下水封洞库为例,分析得知洞室渗水类型主要有断层渗水和优势裂隙渗水,在综合考虑减少渗水量、维持地下水位稳定兼顾围岩稳定性的基础上,提出了"短孔密布"布设注浆孔与"短锚密布"支护的新方式,以此来避免长孔可能打穿隔水岩板所导致的工程风险。
Taking Huangdao underground crude oil storage cavern as an example, it is found that the main types of seepage in the cavern are fault seepage and dominant fissure seepage. Based on the comprehensive consideration of reducing groundwater inflow and maintaining the stability level of underground water and the stability of surrounding rock, a intensive installation method of short grouting holes and short anchor holes is put forward in order to avoid the engineering risk caused by long holes penetrating through water-proof rock slabs.
