Abstract
The invention relates to a rock three-dimensional stress monitoring system and measuring device. The rock three-dimensional stress monitoring system and measuring device comprises a local digital collecting system and a hollow inclusion stress detector. The hollow inclusion stress detector is fixed inside the drill hole of an object to be measured; the local digital collecting system obtains the strain response of the hollow inclusion stress detector during the stress relieving process of a drilling core. The rock three-dimensional stress monitoring system and measuring device has the advantages of achieving synchronization of digital collection and digital measurement, and by combining a collector with the hollow inclusion stress detector, saving operation through a microcomputer terminal, thereby reducing the thermal effect influence on the stress detector, achieving spatial three-dimensional stress computation and saving time and labor.
