低频水平位移锥摆测量仪的研制
|
摘要
针对地质灾害预报中的大地振动测量要求,通过考查国内外现有的各种大地振动测量仪器,提出一种大地水平振动测量的新装置——锥摆系统,并对其结构和原理进行了介绍,结合实际的建造,给出了初步的实验结果。这种测量系统具有二维水平振动位移响应,在大地测量和灾害监控方面具有广泛的应用前景。
Contrapose the request of the earth vibration measurements for the geology disaster forecast,by investigate domestic and international existing various earth vibration measure instrument,a new instrument which can measure low-frequency and horizontal vibration of the earth is introduced--the conical pendulum.The analysis of structure and the principle are introduced,and the basic experiment results are produced.This two-dimension horizontal vibrates response can be applied greatly to the measurement of the earth and disaster surveillance.
