［摘要］在鋼筋-瀝青復合隔震墩的基礎上，研發(fā)了一種以豎向圓柱螺旋壓縮彈簧為隔震單元的新型三維隔震墩，介紹其構造、工作原理及設計理論，并采用剛體塊代替剛度較大的上部砌體結(jié)構，通過模擬地震振動臺試驗研究其在三維振動情況下隔震性能。試驗結(jié)果表明，該新型三維隔震墩能夠同時有效地隔離水平和豎向地震作用，三維隔震效果顯著，且其構造簡單、價格低廉，適于在廣大村鎮(zhèn)地區(qū)的1～3層砌體結(jié)構中使用。

Abstract:A new type three-dimensional seismic isolation pier with vertical cylindrical helical compression springs as the isolation unit was developed on the basis of steel rebar-asphalt compound isolation pier. The structure, operating principle and design philosophy of the device were introduced. Through using the rigid mass block in place of upper masonry structure, earthquake simulation shaking table test was conducted to study the isolation performance of the pier under the condition of three-dimensional vibration. The test results indicate that this kind of new type three-dimensional seismic isolation pier can effectively isolate horizontal and vertical earthquake actions. In addition, three-dimensional seismic isolation effect is obvious, its structure is simple and price is low, which is applicable for one-layer to three-layer masonry structures in the vast rural areas.
Keywords:cylindrical helical compression spring; three-dimensional seismic isolation pier; shaking table test; isolation
