During　the　test,　the　acceleration　responses　of　model　site　and　tunnel,　the　dynamic　soil　pressures　of　structure　and　the　strain　responses　of　tunnel　are　got.　In　this　paper,　the　simulative　effect　of　boundary　is　analyzed.　It　proves　that　the　effect　of　boundary　on　the　earthquake　responses　of　structure　is　avoided　effectively.　At　the　same　time,　the　rules　of　the　earthquake　responses　of　model　system　are　concluded　by　analyzing　the　test　results.　The　strain　responses　of　tunnel　are　analyzed　and　the　distribution　rules　of　strain　in　transverse　section　are　given.　The　dynamic　soil　pressure　in　contact　surface　between　soil　and　model　box　and　between　soil　and　tunnel　are　also　given.　At　the　same　time,　the　liquefaction　phenomena　of　soil　are　described.　Earthquake　cracks　on　ground　surface　and　the　rising　of　structures　are　detected　when　the　strong　ground　motions　are　inputted.
