Step 5, test data is obtained:After the completion of test, the processing module on computer (14) in control software utilizes storage Test data provides the image of the sedimentation value variation of different soil during variation in water pressure and final sedimentation value, or/and provides The image and final sedimentation value of the sedimentation value variation of different soil during the pressure that hydraulic pressure and top apply changes simultaneously.
