摘要
介绍了倾角仪测量结构变形的原理和方法,并对该方法的测量精度问题及其影响因素进行了分析;确定了影响倾角仪测量结构变形精度的2个主要因素;得出了在倾角仪测角精度一定的情况下,倾角仪测量结构变形的精度随所测变形量的增大而提高,且在小变形的情况下所测变形量与变形测量的误差成反比关系和在所测结构的变形量一定的情况下,倾角仪测量结构变形的精度随着倾角仪测角精度的提高而显著提高,且倾角仪的测角精度与变形测量的误差成反比关系的结论,并通过实验验证了分析结果的正确性。
Briefed principles and methods of measurement for structure deformation by inclinometer were introduced in the paper. The measurement accuracy and its influence factors were analyzed. The paper determined two main factors that impact the measurement accuracy, and draw the two conclu- sions： the measurement accuracy improve by the increase of structural deformation and the measure- ment accuracy improve by the angle measurement accuracy, which was verified by test.
