摘　　要：基于振动在建筑物内的传递特性,提出一种新的环境振动预测方法——振动分频传递预测方法。针对北京地铁4号线附近某砌体结构开展现场振动测试试验,并建立了该砌体结构的有限元模型,利用振动分频传递预测方法进行相关数值模拟计算。试验及数值计算结果表明:有限元模拟计算下的结果与实测结果基本一致,验证了该方法能够有效地预测地铁运行引起邻近建筑物的振动响应。According to the transmission characteristics of vibration in buildings,a new method of environmental vibration prediction——the vibration frequency transmission prediction is proposed. A field test of masonry structure vibration in the vicinity of Beijing metro Line 4 is conducted,a finite element model of the masonry structure is established, and the vibration frequency transmission prediction is used for related numerical simulations. The results of test and numerical calculation show that the calculated data by finite element method are in agreement with the test, proving that the new method is able to predict effectively the internal vibration of buildings caused by metro operation.
