Technical field
The utility model is related to the monitorings of field of measuring technique, especially construction, building or ground fractures.
Background technology
Currently, Crack Monitoring instrument can measure the data such as slit width, the translation of crack both sides and dislocation, but have no that it is curved with crack
Roll over distortion measurement function.
Axis where so-called bending deformation, i.e. two edge crack of crack rotates, and plane where both sides is caused no longer to be protected
Maintain an equal level row.When crack by squeezing face to face, it is easy to bending deformation occur, for example, bridge is by huge water impact, impact
Place may be bent.The structural stability on this deformation fracture both sides threatens very big.
Bending deformation do not show the relative translation of crack both sides in the plane, do not show yet crack both sides perpendicular to
Dislocation in plane direction, although it may show in slit width, the angle of plane where being related to both sides because of it,
There is difference substantially with slit width.
