In th is paper, the smi ulative effect of boundary is analyzed. It proves that the effect of boundary on the earthquake responses of structure is avoided effectively. A t the same tmi e, the ru les of the earthquake responses ofmodel system are concluded by analyzing the test results. The strain respon- ses of tunnel are analyzed and the distribution rules of strain in transverse section are given. The dynam ic soil pres- sure in contact surface betw een soil andmodel box and betw een soil and tunnel are als
