Zusammenfassung:PROBLEM TO BE SOLVED: To easily estimate tension resistance of an embedded underground anchor. SOLUTION: There is provided a method of estimating tension resistance of the underground anchor which is embedded in the ground and has a spiral excavating blade at a front end thereof. According to the method, when the underground motor is rotatively driven by a hydraulic motor and embedded in the ground at a predetermined depth, by using a measuring means for measuring driving hydraulic pressure of the hydraulic motor, the tension resistance of the underground anchor is estimated based on the driving hydraulic pressure of the hydraulic motor measured by the measuring means.
