| Abstract: | Grooving and hole drilling method used in measuring prestressing force in prestressed concrete structure members are described.Models of Prestressed sleeper and dual(stretched and compressed)prestressed bridge beam are measured.The dispersion of measuring data is small.Results obtained agree very well with those from calculation,their relative error is less than 20%. |

| Keywords: | prestress stress release method hole drilling method grooving method |
