摘要:
针对压差式静力水准仪在进行沉降监测时受到温度扰动的影响，以工程背景为例，分析了液体温度与压力变化之间的影响关系，建立了基于EIV模型的液体温度与压力的线形模型。模型兼顾温度和压力观测值的随机误差，应用整体最小二乘法对模型参数进行估计，进而根据温度观测值对压力观测值进行校正，间接补偿温度对沉降值的影响。最后应用工程实践数据进行验证，结果表明，利用校正后液体压力对沉降值进行补偿，补偿后沉降值的波动范围减小了67%，能够有效减小由温度变化引起的测量误差，提升监测数据的可靠性和稳定性。
Abstract:
The relationship between liquid temperature and pressure change is analyzed in the engineering background as an example, with the goal of determining the influence of temperature perturbation on the differential pressure hydrostatic leveling system during settlement monitoring. A linear model of liquid temperature and pressure is established based on the EIV model. The model uses the total least squares method to estimate the model parameters while accounting for the random errors of the temperature and pressure observations. It then corrects the pressure observations based on the temperature observations to indirectly compensate for the influence of temperature on the settlement values. The results of applying engineering practice data for verification indicate that when corrected liquid pressure is used to make up for the settlement value, the settlement value’s fluctuation range is reduced by 67%. This effectively lowers the measurement error brought on by temperature changes and enhances the stability and reliability of the monitoring data.
