An apparatus for measuring the bearing stiffness of a track is provided to estimate settlement quantitatively to the limit for maintenance and to judge the urgency of maintenance by checking the displayed result value. An apparatus for measuring the bearing stiffness of a track includes a support shaft(10) provided with at least one hanging projection to descend the weight vertically from the appointed height, a weight(20) coupled to the support shaft to make the vertical descent from the appointed height along the axial direction of the support shaft, a shock absorbing device(30) made of a rubber plate having many projections and provided to the bottom of the support shaft to absorb shock when the weight descends, a measuring device(40) composed of a load cell(42) and a displacement sensor(44) and located on the lower part of the shock absorbing device to measure load of the vertical descent of the weight and to measure displacement by the load, and a data processing device(50) connected to the measuring device electrically to process and display data on the load and displacement measured by the measuring device.
