Abstract: Disclosed are a borehole fracture-deformation-wave velocity integrated intelligent sensing apparatus and method for an engineering rock mass. The apparatus includes an in-hole monitoring execution unit and an out-hole monitoring unit which are connected by a cable; the in-hole monitoring execution unit includes a hole-diameter-adaptive crawling robot and a combined multifunctional probe assembly; the probe assembly includes a high-definition wide-angle camera, a laser radar probe, and an acoustic transceiver probe, and all the probes may be freely combined; the hole-diameter-adaptive crawling robot is of a waterproof sealed shell structure and is capable of charging a pressure inside to realize leakage detection, and the hole-diameter-adaptive crawling robot adopts lift-type electric crawler walking mechanisms capable of automatically adjusting a supporting force to avoid sliding. The apparatus can be used for intelligent long-term monitoring of borehole fracture, deformation and wave velocity.
