This paper looks soil as homogeneous stationary random fields, expatiates the application of the random process in the geotechnical engineering and establishes the basic concept, its assortment and digital feature of random process and random fields, tests whether this random fields is a stationary process and whether it is ergodic, applies correlation function theory and variable function theory in the study of the random fields of soil parameter, acquires the relation of the two theories and draws the conclusion that they are equal essentially, fits the measured curve by using the correlation function method, variable function method and other methods, and acquires the value of correlation distance, applies the random fields theory of soil parameter in actual engineering, estimates the value of elevation and other soil parameters of 92 holes in baoding city and the results are satisfying
將相關函數理論和變異函數理論分別應用於巖土參數隨機場的研究中，通過運用這兩種理論對巖土參數特性的描述，得出這兩種理論的內在聯系及其本質一致性的結論。分別運用相關函數法、變異函數法及其它求解相關距離的方法對實測函數曲線的擬合，得出描述空間相關程度的度量? ?相關距離（或變程） ，對用這幾種不同方法得出的相關距離（或變程）值進行了比較，並對這幾種方法的優劣和實用性做了評比。將巖土參數隨機場理論運用於工程實際，對保定市區某場地的92個鉆孔的各層位的層底標高及其它幾種常見的巖土參數做出了估計，預測結果比較令人滿意。Li chuan - liang, but this formula did not contain any parameter of well penetration. i. e. did not take the perforated thickness into account, it is hard to just perforate the partition board of well in fact, so a modification for it should be made on li ' s formula by adding a critical production rate contributed from the bottom of performed interval to the partition hoard
但是實際油井通常不可能剛好射孔到隔板處，因此，此公式還可以進一步改進：即在油井臨界產量中附加一個由於射孔井段底端和隔板之間距離產生的油井臨界產量。
