It is rare to see a practical project which successfully achieves the seismic isolation ability as well as the vibration isolation capacity. A composite isolation system made up of rubber bearings and laminated rubber sliding bearings was designed. This composite isolation system obtains not only the vertical vibration isolation capacity but also the horizontal seismic isolation capacity. The vertical compression test and the horizontal static stiffness test, were done on the model bearings and related tests were done on the prototype bearings. It is shown that the parameters of the bearings gained by the tests accord with the designed ones. Thus, this composite isolation system, which can achieve the intended goal, is an ideal composite isolation device.Keywords: rubber bearing; sliding bearing; mechanical property; experimental study*上海市科學技術(shù)委員會科研項目（09dz1207800），上海市城鄉(xiāng)建設(shè)和交通委員會科研項目（重科2010-002）。作者簡介：李亞明，總工程師，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，Email:liym@siadr.com.cn。參考文獻［1］周福霖. 工程結(jié)構(gòu)減震控制［M］. 北京: 地震出版社, 1997.［2］魏陸順, 周福霖, 任珉. 三維隔震（振）支座的工程應用與現(xiàn)場測試［J］. 地震工程與工程振動, 2007,27(3): 121-125.［3］杜修力, 廖維張, 杜義欣, 等. 智能隔震系統(tǒng)的沖擊振動臺試驗［J］. 解放軍理工大學學報: 自然科學版, 2007, 8(6): 689-694.［4］FUJITAS, KATOE, KASHIWAZAKIA.
