PURPOSE:To measure deformation with high accuracy by enabling the measurement of data as lines enclosing the range of a measuring object with substantially no discontinuity. CONSTITUTION:A section 71 to be measured is segmented by 1- several prescribed lengths 72, 73-, and average strain gages 74, 75- each having the instrument length equal to a prescribed length by each of said segments. Both end parts of said gages 74, 75- are connected in a longitudinal array by using connecting fittings 76 to the length conforming to the above-described section to be measured. Concrete sticking pieces 77 are mounted to both end parts in the section to be measured. A series of the gages 74, 75- which are connected of plural pieces in the above-mentioned way are provided respectively in combination with a pair of strain measuring lines L1, L2. If such measurement constitution is adopted, the specific data which is the data of an extremely local place is leveled off in each segment and has the virtually negligible values; therefore, the processing as the data extremely useful in data analysis is made possible. |
