摘要
根据土性随机场理论 ,对递推空间法及递推空间法的变形进行了讨论和辨析 .并通过工程实例计算 ,提出了实用的相关距离参数n 的确定方法 .分析表明递推空间法的土性空间均值条件对计算结果的影响不能忽略 ,递推时若不满足土性空间均值相等而引起的误差是相当大的 .
Based on probabilistic modeling of soil profiles, recurrence space average method and its deformation are discussed and analyzed. The method of finding n * value,a parameter is presented through computation of auto covariance distance. The computation and analysis indicate that the influence of the average value condition of soil profiles can't be disregarded on auto covariance distance by means of recurrence space method, and if the equal average conditions can't be guaranteed, the error is fairly great.
