Abstract: A method, belonging to the field of road disease prevention technologies, for constructing a simulation model for roadbed diseases, a test method, and a system, where a simulation model for roadbed diseases is first constructed, and based on the model, an experimental method is performed to simulate diseases such as roadbed settlement, cracks, loosening, and pipeline breakage. Data of multi-sensing devices is associated with different diseases in different control groups, data statuses of various roadbed diseases in complex scenarios are acquired, and data patterns are summarized through control tests, to obtain sensor thresholds when the diseases occur in actual roadbed conditions, thereby providing a basis for road disease prevention.

Abstract: A delivery apparatus, a delivery system, a delivery method, an electronic device, and a computer readable storage medium are disclosed. The delivery apparatus includes a movable detachably and electrically connected with a cabin, where the movable chassis is configured to include: a first controller mounted inside the movable chassis, and a moving component mounted at a bottom of the movable chassis and connected with the first controller to drive the movable chassis and the cabin to move to a target position according to an instruction of the first controller; the cabin is configured to have one or more accommodation spaces for accommodating to-be-delivered objects. The technical solution greatly improves the delivery efficiency and reduces the delivery cost.

Abstract: The present invention provides a fracturing process, which comprises the following steps of: injecting a fracturing fluid into the formation to cause fractures in the formation and stopping the injection of the fracturing fluid after the fracture as produced reaches a preset requirement; injecting a phase transition material fluid capable of undergoing a phase transition reaction at a preset temperature and a delayed heat generating agent into the formation, wherein the delayed heat generating agent functions to generate heat after the injection of the phase transition material fluid is substantially completed, so as to cause a phase transition of the phase transition material fluid to complete the fracturing. The technical solution provided by the present invention can effectively reduce the friction resistance of the pipe string; moreover, the use of a delayed heat generating agent can effectively control the initiation and progress of the phase transition reaction.
