The utility model discloses a multrirange soil pressure cell calibration device, solve current soil pressure cell demarcation mode exist the error big, waste time and energy and problem that the result is unstable. The utility model discloses a normal sand for placing soil pressure cell's demarcation bucket is loaded in this demarcation bucket, is just buried soil pressure cell wherein to and place the load plate on the normal sand upper surface. The utility model relates to a rationally, convenient to use, low cost, the demarcation mode of its adoption is because the practical application environment with soil pressure cell is comparatively similar, therefore not only measuring error is little, labour saving and time saving moreover, the result is stable, therefore has not only solved prior art's problem well, unified soil pressure cell, especially multiple range demarcations are standard to provide good foreshadowing in earlier stage in order to form moreover. 本实用新型公开了种多量程土压力盒标定装置，解决现有的土压力盒标定方式存在误差大、费时费力、且结
