摘要

为了减小道路交通汽车荷载对广州市番禺万博商务中心地下空间结构产生的低频振动影响

研发一种新型的钢弹簧浮置板隔振道路。应用ANSYS软件分别建立钢弹簧浮置板、地下空间、浮置板和地下空间结构的三维有限元模型

对这3种不同结构进行模态分析

并进一步研究了传导比。结果表明: 设计的浮置板道路基频为8.69 Hz; 地下空间基频为15.69 Hz; 浮置板与地下空间整体结构基频为7.33 Hz; 从振型上看

低频时主要体现为浮置板的振动

中高频时主要为地下空间结构顶板的振动; 3种结构的传导比峰值均出现在第一阶固有频率附近

地下空间结构在增加钢弹簧浮置板后传导比最大为0.878。钢弹簧浮置板道路可起到良好的隔振效果。

Abstract

In order to reduce the impact of road traffic load on the low-frequency vibration of the underground space structure of the Panyu Wanbo Business Center in Guangzhou

a new type of vibration isolation road with steel spring floating slab was developed. 3-D finite element models of steel spring floating slab

underground space

floating slab and underground space structure were established by using ANSYS software. A modal analysis of these three different structures was carried out

and transmission ratio further studied. The results showed that: the fundamental frequency of floating slab road is 8.69 Hz; the fundamental frequency of the underground space is 15.69 Hz; the fundamental frequency of the floating slab and underground space structure is 7.33 Hz; the vibration modal of floating slab was mainly in the form of low frequency

and the vibration modal of roof in the underground space mainly in the form of medium and high frequency; the peak value of transmission ratio of the three structures occurred near the first natural frequency

and the ground frequency was mainly in the form of vibration. The maximum transmission ratio of the lower space structure was 0.878 when the steel spring floating slab was added. Steel spring floating slab road had good effects of vibration reduction and isolation.
