Abstract
The invention discloses a performance test system and method for a reinforced geotechnical structure under the action of multi-field coupling. The technical problem that in the prior art, multi-field coupling and actual boundary conditions are difficult to simulate in an indoor large dynamic triaxial test is solved. The performance test system comprises a working condition simulation device and a measurement device. The working condition simulation device comprises: a supporting unit used for supporting the reinforced geotechnical structure; a vertical loading unit, which comprises a loading plate and a driving mechanism for driving the loading plate; a transverse restraining unit, which comprises a restraining plate and a supporting mechanism for supporting the restraining plate; a dry-wet circulation control unit, which comprises a water circulation mechanism and a drying mechanism; the measurement device comprises: a first distance measuring unit used for measuring vertical displacement; a second distance measuring unit used for measuring transverse displacement; a pressure monitoring unit used for measuring the pressure borne by the reinforced geotechnical structure; and a state monitoring unit used for measuring any several of the accelerated speed, the temperature and the water content of the reinforced geotechnical structure.
Description
technical field [0001] The present invention relates to the technical field of geotechnical engineering and railway engineering, in particular to the technical field of performance research of reinforced geotechnical structures under the action of hydro-thermal-mechanical coupling, specifically, to the technical field of reinforced geotechnical structures under the action of multi-field coupling performance testing system and method. Background technique [0002] Geocell reinforcement, as a form of three-dimensional reinforcement device, has been widely used in many fields at home and abroad. Geocell reinforcement is achieved through the confining effect of the side wall, friction between the upper and lower interfaces of the reinforced layer, and stress diffusion and flexible rafts. The subgrade effect can improve the overall stability of the subgrade structure and reduce settlement. [0003] At present, the common method for testing the dynamic performance of reinforced g...
