摘　　要：目前现行的岩体分类标准是以评价围岩稳定性为目的的,不能满足工程对围岩渗透性的要求。以现行岩体分类标准和水封洞库工程特殊性为基础,考虑岩体质量和岩体导水性,并将结构面的连通率、张开度、产状等因素引入评价标准,采用施工勘察、超前地质预报等技术手段,建立了一种服务于水封洞库施工的水文地质分类方法。水文地质分类指导洞库围岩的注浆工作,采用地质雷达和压水试验对注浆效果进行检验,确保了洞库围岩稳定性和水封性。The current classification standards of rock mass, based on evaluation for the stability of surrounding rock mass, can not meet special requirements of underground projects on permeability of surrounding rock mass. Based on the analysis of the current rock mass classification standards and the particularity of underground crude oil storage cav- erns, the evaluation of rock permeability and the quality of rock mass were considered at the same time. The hydrologi- cal geology classification method for the service of the construction was established in order to objectively analyze the permeability of surrounding rock based on the technical means of the detailed investigation, construction survey and ad- vanced geological prediction, of which the connecting rate of the structure, the opening degree and preferred structural plane＇ s attitude were introduced into the evaluation criteria. The hydrological classification direct guide grouting, and the effect of grouting was inspected by using the geological radar and packer test to ensure the stability and water seal of underground cavity.
