Zusammenfassung:	The utility model provides a fiber bragg grating measuring device, which comprises an optical fiber, a detection part, a protective shell and a probe cap, and is characterized in that the detection part is arranged in a gap of a rock to detect the pressure change in the gap of the rock, and the optical fiber is connected with the detection part; the protection shell is arranged outside the detection part and is used for protecting the detection part; the probe cap is connected with one end, far away from the optical fiber, of the protective shell and is used for protecting the detection part. By adopting the scheme, the detection part extends into the gap of the rock and detects the pressure generated by the rock, the optical fiber is connected with the detection part and is used for transmitting a signal of the detection part, the protective shell and the probe cap are arranged outside the detection part and are used for protecting the detection part, and the probe cap is clamped in the rock, so that the roc
