Method for testing sliding friction coefficient of split type heavy load shifting device

The invention relates to a method for testing the sliding friction coefficient of a split type heavy-load displacement device, which comprises the following steps of: before integral sliding construction of a larger structure, constructing an equal-proportion heavy-load displacement device, applying a vertical load until the pressure is stable, applying a horizontal force by a horizontal traction device, further enabling a sliding device to slide horizontally, recording the size of the load, and testing the sliding friction coefficient of the heavy-load displacement device. And the sliding friction coefficient in the actual operation process is determined through the vertical force and the horizontal force. The heavy load shifting device is of a split type structure, the horizontal traction device is connected with the fixed building and the sliding box to provide horizontal force, the sliding box is arranged above the sliding groove, the vertical jacking jack is arranged in the sliding box to provide vertica
