本文介绍了地脉动测量在拱坝坝肩山体振动特性分析中的应用,讨论了各个测点间地脉动过程的空间相关分布,通过实例对量测方法和分析方法进行了说明。 一、引言 对环境脉动所激发的结构振动进行量测分析,由此得到建筑物的自振特性,这是结构振动分析的一种重要手段。当这一方法用来研究坝肩山体的振动特性时,主要有两方 This paper introduces the application of ground-based pulsation measurement to the analysis of vibration characteristics of dam abutment in arch dam, and discusses the spatial distribution of ground-pulsation process at each measuring point. The measurement methods and analysis methods are illustrated by examples. I. INTRODUCTION The structural vibration excited by environmental pulsation is measured and analyzed, and the natural vibration characteristics of the building are obtained. This is an important means of structural vibration analysis. When this method is used to study the vibration characteristics of a dam body, there are mainly two parties
