摘　　要：基础隔震是一种创新、可靠、发展潜力巨大的新型技术,经过几十年的发展,在基础理论与实际应用中都取得了很大的进步。本文简要介绍了基础隔震的基本原理、必要条件及几种常见的隔震装置,详细介绍了近年来国内基础隔震领域的最新理论进展与实践成果,重点介绍了钢筋沥青隔震、玻璃珠石墨滚动滑移体系、砂垫层滑移体系等农村基础隔震技术,目前隔震研究主要为造价偏高的橡胶隔震,不适于在村镇地区推广,村镇建筑的隔震研究、应用仍很落后,针对这一现状,提出了研发、推广一种廉价、高效、适于村镇建筑的基础隔震装置的迫切性。Base isolation is a new technology which is innovative and reliable,and it has huge potential for development. After decades of development,it has achieved great progress in the basic theory and practical application. The basic principles and necessary conditions of base isolation are introduced,and several common isolation devices are presented. The latest theoretical progress and practical achievement in the field of base isolation in recent years,especially steel-asphalt isolation,glass bead-graphite roll slip system,sand cushion slip system and other rural base isolation technologies,are elaborated. However,the present isolation research mainly focuses on high-cost rubber vibration one which is not suitable for promotion in rural areas,where also suffered from serious earthquake disasters. In view of that,the urgency of the study and the promotion of base isolation device which is cheap,efficient and suitable for rural construction are proposed.
