Abstract: In general, various aspects of the techniques enable predictive modeling for forged components. A computing device comprising a memory and a processor may be configured to perform the techniques. The memory may store a trained machine learning model that associates training features extracted from data representative of a plurality of training forged components to a plurality of training model results. The memory may also store data representative of a target forged component. The processor may perform a geometrical analysis with respect to the data representative of the target forged component to extract target features, and apply the trained machine learning model to the target features to obtain predicted model results for the target forged component. The processor may also output the predicted model results.

Abstract: A method of treating tunnel collapse includes leveling a collapse body and moving a pavilion support under the collapse cavity, lifting a shield plate until a lower edge of the shield plate surpasses a contour line of an initial supporting arch of a tunnel, connecting a bottom column and inserting a padding plate under a column. If the hydraulic prop retracts, the column, the bottom column, the padding plate and the hydraulic prop bear a load from the shield plate. Mounting and connecting the initial supporting arch, welding the intersection point of the column and the initial supporting arch, cutting off the column in the initial supporting arch. Transferring the load of the shield plate from the pavilion support to an initial supporting shed, spraying fast-setting concrete to a grid arch to form a closed shell, and pumping filling material to fill the space of the collapse cavity.

Abstract: A method of treating tunnel collapse includes mounting a shield plate, a column, a support column to form a combined support and moving the combined support onto an operation platform, lifting up the combined support, and enabling the height of canopy to be greater than the height of an initial supporting arch. Actively contacting a surface of a collapse cavity by a fixed support column and bearing a load, and lifting a movable support column to the top of the collapse cavity and bearing a load. Mounting an initial supporting arch, and welding the initial supporting arch with the support column. Removing a hydraulic prop after the support column contacting the initial supporting arch is cut off and the load of the shield plate is transferred to a supporting shed. Mounting an exhaust pipe and a filling material pumping pipe, and pumping a filling material into a collapse cavity space.
