二维垂直摆倾斜仪对地倾斜的测量
|
摘要
本文提出了一种利用二维垂直摆倾斜仪同时测量2个方向地倾斜信号的新方法,给出了二维垂直摆倾斜仪对地面倾斜信号的测量结果,介绍了二维垂直摆倾斜仪的工作原理,分析了垂直摆的热噪声。初步实验结果表明,二维垂直摆倾斜仪对地倾斜信号较灵敏,已观测到地倾斜潮汐。
A new method to measure crustal tilt in two directions at the same time with two-dimension vertical pendulum tiltmeter is proposed,and the measurement result of crustal tilt with two-dimension vertical pendulum tiltmeter is presented in the paper.The operation principle of two-dimension vertical pendulum tiltmeter is introduced and its thermal noise is analyzed.Preliminary experimental result shows that the two-dimension vertical pendulum tiltmeter is very sensitive to crustal tilt,and the crustal tilt tides were observed.
