The　global　response　of　underground　structures　subjected　to　ground　shock　is　investigated　theoretically,　experi-mentally　and　numerically.　Non-zero　rise　time　of　ground　shock　is　taken　into　account　in　the　theoretical　prediction.　A　scale　model　field　test　is　conducted　to　examine　the　prediction　accuracy,　suggesting　that　the　conventional　method　without　ground　shock　rise　time　may　result　in　over-design,　while　the　present　approach　with　rise　time　more　reasonably　predicts　the　global　acceleration　response　which　is　the　excitation　to　the　affiliated　devices　inside　the　structure.　Subsequently,　shock　response　spectra　of　inside　devices　with　mounting　are　established　to　evaluate　the　shock　environment　within　the　underground　structure.　Numerical　simulation　further　complements　the　study.　With　combined　approach,　the　key　factors　influencing　the　global　response　and　in-structure　shock　of　underground　structures　are　discussed　in　detail,　whose　findings　facilitate　more　reasonable　design　of　underground　structures　in　terms　of　shock　environment　assessment　and　mitigation.
