在对影响水位变化的各因素给出合理计算的基础上,用逐步回归方法分析了山东、兖州深井27天的水位整点值资料,较好地消除了诸因素对水位的影响,求出的残差△(t)曲线呈随机波动,均方差σ=6.97毫米,复相关系数R=0.987。对诸因素影响水位变化的力学过程做了初步说明,给出了因素的偏回归系数。提出对气压做滤波分析,更精确认识气压效应的设想,并做了尝试计算,初步说明了气压与水位的近线性而非线性的关系。
Based on the reasonable calculation of each factor affecting the water level change, the whole point data of 27-day water level in Shandong and Yanzhou deep wells were analyzed by stepwise regression method, and the influence of various factors on the water level was well eliminated. Residual △ (t) curve showed random fluctuations, mean square deviation σ = 6.97 mm, complex correlation coefficient R = 0.987. The mechanical processes that affect the water level change are preliminarily described, and the partial regression coefficients of the factors are given. The idea of making pressure analysis on air pressure and getting a more precise understanding of the effect of barometric pressure is put forward. Attempts are made to calculate the relationship between the pressure and the water level, which is linear but not linear.
