地倾斜双轴垂直摆倾斜仪测量方法研究

摘要

In this letter, a biaxial vertical pendulum tilt meter for measuring the micro-tilt of superficial coat of the earth in two directions is presented, Its basic structures and principles are also described. The sensitivity of the device was calibrated experimentally with a piezoelectric transducer (PZT). Experimental results show that the biaxial vertical pendulum tiltmeter can measure two orthogonal direction tilt signal, so it verily reflect the tilt signal where a dot in earth. The tilt tides in two directions of EW (east and west) and SN (south and north)has been observed with biaxial vertical pendulum tiltmeter and with a precision of 10-9 rad.%介绍一种可同时测量两个正交方向(例如:东西向和南北向)地壳倾斜的双轴单摆体结构的垂直摆倾斜仪的基本原理,并给出其结构设计和初步的实验结果.实验结果表明,地倾斜双轴垂直摆倾斜仪能同时测量两个正交方向的倾斜信号,分辨率达到10-9 rad数量级,能够清晰记录地倾斜固体潮汐信号.
