In order to improve the structural safety and stability of tunnels crossing stick-slip fault, an indoor model test on effect tunnel antibreaking measures under influence fault movements was conducted. Using contact pressure, longitudinal strain, factor, compared analyzed 5 kinds operating conditions, mainly including no measures, strengthening, strengthening reducing dislocation layer, joint, joint. The results showed that strain pressure changed markedly (from severe change more uniform change) when were adopted in test, layer/joint or layer structure is very limited by only taking measures. obvious using method, minimum factor increased than 8 times. resisting remarkable adopting 25.45 can provide reference for design high earthquake intensity dangerous mountainous areas.
