The invention relates to the technical field of engineering monolithic track bed construction, in particular to an anti-stray current test method for subway monolithic track bed construction, which comprises the following steps of: in the construction process before track bed concrete pouring, carrying out any following tests: steel rail internal resistance test; test of the internal resistance ofa ballast bed drainage net; test of transition resistance between the steel rail and the ballast bed drainage net; test of transition resistance between the steel rail and an adjacent structure; andtest of the transition resistance between the ballast bed drainage network and the adjacent structure. Compared with the prior art, the method has the advantages that a set of complete stray currentconstruction detection method and construction quality control measures in the construction process are provided, and the hidden danger of stray current leakage can be fundamentally controlled and reduced to a large extent; dete
