摘要:
针对当前静力水准仪液管因环境振动、温度变化等因素，导致静力水准仪测量误差增大，测量稳定性差、数据无法使用等问题，以液压式静力水准仪为研究对象，分析在施工时受到环境振动和温度变化导致的测量误差，通过搭建水准仪试验平台，完成了不同频率、不同幅值的振动误差影响试验和40组静力水准仪温度实验，并通过单峰函数InvspoLy拟合，得到了改进的温度补偿公式，通过验证，改进后的静力水准仪在0 mm～1000 mm测量范围内测量精度≤±0.05%FS；沉降值误差明显降低，仿真效果与测试结果一致，验证了其有效性。
Abstract:
In view of the problems such as the increase of the measurement error of the static level, the poor measurement stability and the unavailability of data caused by the environmental vibration and temperature change of the current static level liquid pipe, taking the hydraulic static level as the research object, this paper analyzes the measurement error caused by the environmental vibration and temperature change during the construction, and completes the measurement of different frequencies The vibration error influence test of different amplitudes and 40 groups of static level temperature experiments are carried out, and the improved temperature compensation formula is obtained by fitting the unimodal function invspoly. Through verification, the measurement accuracy of the improved static level is ≤± 0.05% FS in the measurement range of 0mm ~ 1000mm; The error of settlement value is significantly reduced, and the simulation effect is consistent with the test results, which verifies its effectiveness.
