The invention discloses a defective cable and support angular displacement identification method based on angular monitoring of temperature change. The method comprises the following steps of: on the basis of angular monitoring, judging whether a mechanical calculation reference model of a cable structure is required to be updated by monitoring the temperature of the cable structure and environment temperature, and thus obtaining the mechanical calculation reference model of the cable structure, into which the temperature of the cable structure and the environment temperature are recorded; and on the basis of the mechanical calculation reference model, acquiring a unit damage monitored amount unit change matrix by calculation. A non-inferior solution of the current nominal damage vector of an evaluated object is obtained by calculation according to an approximately linear relationship between the current value vector of monitored amount, the current initial value vector of the monitored amount, the unit damage monitored amount unit change matrix, a unit damage or unit angular displacement vector and the to-be-obtained current nominal damage vector of the evaluated object, so a damaged cable, a loosened cable and support angular displacement can be quickly identified when the temperature change occurs.
