Abstract The main research focuses on the errors effect of vertical pendulum tiltmeter platform leveling in three aspects,and proposes the improved methods. On the basis of the existing platform leveling tiltmeter data, the structural and environmental factors in the systematic errors arising from tiltmeter are analyzed and calculated. By improving the mechanical structure and the platform components parameters to reduce errors,the technical requirements is achieved.
