摘要
该文详细分析了传感器、测斜仪和全站仪的精度,特别从电学的角度对传感器的误差进行了探讨,并通过其测量力学参数的原理得到其最后测量物理量的精度;对引起测斜仪的误差的因素进行了研究并定义了测斜仪测量的误差。该文的分析结论可以给岩土工程室内模型实验、现场实验以及监测数据提供数据可靠性以及精度分析依据,这样监测得到的数据就更加精确、可靠。
The accuracy of the sensor,inclinometer and total station are analyzed detailly in the paper.Particularly,the sensor error is discussed from the electricity angle,and through the principe of measuring the mechanical parameters,the accuracy of physical measurement is gotten. The factors that cause the error of inclinometer are studied,and the measurement error of inclinometer is defined. In this paper,the analytic results can provide the data reliability and accuracy analysis basis for geotechnical laboratory model experiments,field experiments and monitoring data. The monitoring data obtained by that are more accurate and reliable.
