The invention provides testing equipment for simulating mutual influence of multiple tunnels. The testing equipment comprises a simulation tank, a mold plate and at least two tunnel models, wherein apart of the area on the front side of the simulation tank is hollowed; the mold plate is detachably fixed on the front side of the simulation tank; the hollow area of the simulation tank is covered bythe mold plate; at least two holes are formed in the mold plate; the tunnel models penetrate through the holes and penetrate into the simulation tank; the tunnel models are fixed on the mold plate. By adopting the testing equipment, expected working conditions can be rapidly simulated for study purposes according to influence of relative angles and net distance variation of multiple tunnels, anddifferent working conditions can be simulated.
