    Abstract: An automatic test system and method for mechanical parameters of surrounding rock applicable to a TBM. The system includes: an aggregate portion collecting a rock slag in a TBM tunneling process in real time; a gripping portion gripping any rock slag from obtained rock slags; a visual processing apparatus performing three-dimensional imaging for a rock slag under test in an infrared ranging manner; calculating positions of loading points for an abrasiveness test experiment, and determining, based on a spacing between loading points, whether rock slag under test meets a requirement; and determining actual positions of loading points if the rock slag under test meets the requirement, and determining a region, on a surface of rock slag, that meets a set condition as an action region for abrasiveness test experiment; and a rock abrasiveness test apparatus automatically performing an abrasiveness test for a rock slag under test that meets a requirement.

    Abstract: A multi-scale unsupervised seismic velocity inversion method based on an autoencoder for observation data. Large-scale information is extracted by the autoencoder, which is used for guiding an inversion network to complete the recovery of different-scale features in a velocity model, thereby reducing the non-linearity degree of inversion. A trained encoder part is embedded into the network to complete the extraction of seismic observation data information at the front end, so it can better analyze the information contained in seismic data, the mapping relationship between the data and velocity model is established better, then the inversion method is unsupervised, and location codes are added to the observation data to assist the network in perceiving the layout form of an observation system, which facilitates practical engineering application. Thus a relatively accurate inversion result of the seismic velocity model when no real geological model serves as a network training label can be achieved.
