The invention provides a water-lubricated bearing frictional wear test platform for simulating a sediment working condition and a test method. The platform comprises a main transmission system which is connected with a tail shaft and outputs power, the tail shaft is connected with a to-be-tested water-lubricated bearing, and a radial loading system achieves rising and lowering of the other end ofa loading support through reverse internal threads at two ends of a double-end nut, so that the water-lubricated bearing is loaded by utilizing the lever principle. A multi-working-condition fitting system comprises a lubricating medium box, a temperature adjusting device, a stirrer and a lubricating medium pump. A three-dimensional force sensor measures the radial, circumferential and axial forceof the water-lubricated bearing; and a data processing controller calculates the initial loading force between the water-lubricated bearing and the tail shaft and a friction coefficient in the friction process of the water-lu
