Problems solved by technology

[0004] The multi-disaster simulation experiments for tunnels in the prior art need to be carried out step by step, because the buildings for the simulation experiments of various disasters are all set outside the specimens. Various disaster experiments will conflict with each other in the process of simulating disaster experiments. For example, if static load, dynamic load, liquid corrosion experiment and electric corrosion experiment are carried out on the outside of the test piece at the same time, the above-mentioned experimental devices are too numerous to be installed on the test piece at the same time. If it is installed forcibly, it will cause conflicts during the experiment. Therefore, how to implement multiple experiments at the same time is a technical problem that needs to be solved at present.

Description

technical field [0001] The invention relates to the field of simulation testing for disaster prevention and mitigation of tunnel buildings, in particular to a multi-hazard coupling experiment system for simulating tunnels and an experiment method thereof. Background technique [0002] With the rapid development of my country's economy and the accelerated urbanization process, the urban population is highly concentrated, which in turn brings a series of social problems, such as traffic jams, environmental pollution, noise pollution, repeated road excavation and dense overhead lines. In this regard, many cities are actively building underground infrastructure, such as underground tunnels, subways and urban underground pipe corridors. [0003] However, since underground tunnels, subways and pipe corridors are all special long and narrow closed underground structures, fire has become one of the most serious disasters. For example, once a fire breaks out in a tunnel, it will not...
