The invention discloses a holding pole working state monitoring method, which comprises the steps of establishing a holding pole finite element model, and applying a simulation load to the holding pole finite element model; weak parts of the derrick finite element model under all working conditions are obtained; according to the numerical simulation result, a strain sensor is arranged on the holding pole entity and used for monitoring the strain condition of the position; acquiring a strain monitoring value of the strain sensor, judging whether the strain monitoring value is greater than the maximum strain bearing value of the corresponding position or not, if so, stopping running and giving an alarm, and if not, repeating judgment. According to the holding pole working state monitoring method, the weak parts are obtained through finite element simulation. The positions are the positions where strength and instability damage is most likely to happen. The strain monitoring is conductedon the weak parts. It can be guaranteed that damage is avoided as long as the strain of the positions does not exceed the corresponding maximum strain bearing value. The weakest position is mainly monitored. The stress condition of the holding pole entity can be accurately reflected.
