摘　　要：对沙介质中的储罐采用外涂层加牺牲阳极的阴极保护措施。阳极位置、罐体周围沙介质电阻率及其随深度的变化是影响地下储罐阴极保护的主要因素。A cathodic protection method was conducted for underground storage tanks in a sand medium by using external coatings and sacrifice anode.The anodic locations,the resistivity of the sand medium surronding the storage tanks and the changes of the resistivity with various depths were major factors affecting the cathodic protection,

关 键 词：阴极保护 沙介质 电阻率 地下储罐 液化气 气罐
