The utility model discloses a test device for simulating shield segment joint water leakage and grouting treatment, which belongs to the technical field of tunnel shield test equipment, and comprises a model box, a water circulation assembly and a grouting assembly, the model box comprises a fixed plate and a movable plate connected with the fixed plate in a sliding manner, an adjustable gap is formed between the fixed plate and the movable plate, and the adjustable gap is used for simulating an open seam between segments; the water circulation assembly is communicated with the model box and is used for simulating actual water pressure for the soil body in the model box; the grouting assembly is connected with the fixing plate and communicates with the containing cavity. The utility model solves the problem of poor treatment effect caused by difficult selection of reasonable grouting parameters due to limitation of various actual special conditions in the process of treating joint water leakage in the prior a
