Abstract

The invention discloses an intelligent simulation earthquake loading test box. The test box comprises an earthquake simulation exciter, an acceleration sensor, a sand cushion layer, a model box support, a moisture sensor, a rainfall simulator, a measurement monitoring system, a manual operation panel, a data acquisition controller, an underground water level simulation controller, a computer and software system, a data storage transmitter, a pore water pressure sensor, an electromagnetic automatic control valve, a vertical load loading system, a power supply and a model box. According to the technical scheme provided by the invention, earthquake load simulation can be realized in a model test in a shock wave form, and the damage effect of an earthquake on the internal structure of the sample is truly reflected. According to the technical scheme provided by the invention, earthquake load effects in two directions can be simulated, namely earthquake simulation loading under a two-dimensional condition is realized, and the earthquake simulation loading is consistent with an action process in an actual earthquake.

Description

Technical field: [0001] The invention belongs to the field of geotechnical engineering, in particular to an intelligent simulated earthquake loading chamber. Background technique: [0002] Earthquakes are a number of natural disasters, often after an earthquake geotechnical engineering structures can cause damage or even collapse occurred damage, cause serious damage to the project. Earthquake simulation test technique by combining a predetermined model model test in the case of seismic loading rock mass can be tested in response to earthquake accurately, better services for the disaster prevention and reduction. Prior art test methods are often carried out by shaking table and dynamic triaxial seismic load simulation so on, or by a method simulated seismic loading blasting site. Wherein only a dynamic triaxial specimens to simulate small-scale earthquake damage, the scene can be simulated response blasting works of the large slope and tunnels under seismic action, but due to the...
