The problem to be solved by the invention is how to make a crack monitor have a bending deformation monitoring function. A method for using a monitor having a crack bending deformation measuring function includes the following steps: a, installing the monitor and recording the initial data of respective sensors; b, after some time, according to the new data measured by the sensors, calculating the crack deformation at a data monitoring end, wherein the calculation method is characterized in that the bending deformation is the change value of an angle sensor; the displacement is the change valu...
