摘　　要：通过对黄河中游某水电站除险加固工程区域地质构造、水文地质条件、钻孔压水试验、多年地下水观测、地下水渗流场等因素的研究,针对工程区岩溶承压水影响这一主要工程地质问题,确定工程区各岩层岩体的渗透系数、分层地下水位,并提出承压水对施工影响的相应处理措施。Based on the study of regional geological structure,hydrogeological condition,water-pressure test,years of groundwater monitoring information and seepage field,it is found that the influence of karst confined water is the key engineering geological problem in the project area.Furthermore,permeability coefficient and ground water level of each formation is determined,and measures for confined water which may affect the construction of reinforcement are proposed.

关 键 词：水电站除险加固 地下水 岩溶承压水 施工围堰
