The utility model discloses an underground cavern simulation modeling experiment device based on temperature factor, including the casing with set up the sample load -bearing platform in the casing, still including the temperature regulation and control system that can change the sample temperature value with be used for under the different temperatures value load loading system to the sample load application, temperature regulation and control system including set up in the casing and be used for to the heating member of sample heating with set up in the casing and be used for detecting the temperature sensor of sample temperature, can make the underground cavern simulation sample in the casing reach different temperature values through temperature regulation and control systems, and carry out the load loading to the sample respectively under the temperature value of difference, thereby gather country rock atress the warp condition of sample under the different temperatures value, can carry out real simulation in the influence under the different temperatures effect to tunnel excavation engineering or other underground cavern's country rock atress and deformation behaviour, can accurate reflection actual conditions, fairly good application prospect has in the aspect of deformation and the stress etc. Of test hole room.
