摘　　要：通过对比几种常见形式的隔振基础,探讨低频敏感设备隔振基础的设计选型。指出对于低频敏感设备,可采用与周围土体刚性连接的大块混凝土隔振基础形式及大块混凝土基础加隔振垫的隔振基础形式。对于低频振动隔振要求极为苛刻的设备或者周边的环境振动条件比较差的情况,建议采用直接建在基岩上的钢筋混凝土桩基础形式。不推荐采用混凝土基础加隔振沟或混凝土大块基础加隔振砂的隔振基础形式。There are several kinds of isolation foundation discussed in this paper, in order to find suitable isolation foundation for low frequency sensitive equipment. For low frequency sensitive equipment, it is pointed out that the concrete foundation rigid connecting with earth and the concrete foundation with rubber isolator at bottom are viable. For the low frequency sensitive equipment with harsh terms or in tough condition, it is recommended to use the concrete isolation foundation built on the rock basement. The isolation trench and the concrete isolation foundation with sand at bottom are not recommended.
