In this study, it is assumed that it is not a point value but an average over certain physically meaningful volume of soil that should satisfy a specified value of physical index of soil in soil construction quality control. This is because, in the recent years, some new measurement devices that are able to measure these quantities much easier and economically than the traditional methods, which resulted to take much more measurement than the past, and tend to find many measurements to undershoot the specified values. This was not experienced in the past for the earthworks shoes quality is considered to be the same.A way to model the qualities of soil by a random process is introduced, and level crossing of a moving average process is discussed. The main outcomes of the research are as follows:( 1 ) A method is developed based on Akaike Bayesian Information Criterion to identify autocorrelation function from considerably small samples, say 10 to 20 observations.( 2 ) Based on the autocorrelation structures identified, interpolation methods are developed based on the idea of Kriging.( 3 ) A method is developed for construction control of soil compaction and soil improvement based on the moving average process and level crossing probability.( 1 ) and ( 3 ) are considered to have much originality.

在这项研究中，假定它不是一个点值，而是某些物理上有意义的土壤的平均值，应满足土壤构造质量控制中土壤物理指数的指定价值。这是因为近年来，一些新的测量设备能够比传统方法容易和经济地测量这些数量，这导致比过去进行了更多的测量，并且倾向于找到许多测量值以降低指定值。过去，这不是Earthworks鞋子质量的经历。这是一种通过随机过程对土壤质量进行建模的方法，并讨论了移动平均过程的水平穿越。研究的主要结果如下：（1）基于Akaike贝叶斯信息标准开发了一种方法，以确定相当小的样本的自相关功能，例如10至20个观测值，（2）基于确定的自动相关结构，基于确定的自动相关结构，基于KRIGIGN的构造和构造的构造方法是基于构造的构建方法。概率（1）和（3）被认为具有太多的独创性。
