摘要
阐明了平稳随机场的空间统计特性,根据平稳随机场各态历经性概念,讨论了土层满足各态历经性的条件,以及计算空间平均方差和相关距离的公式。并结合工程实例,分析了空间平均方差计算的影响因素。
The space statistical characteristics of a smooth stochastic field are elaborated. On the basis of concept of smooth stochastic field ergodicity, conditions that soil strata are satisfied with ergodicity are discussed; and equations of calculating space mean variance and correlative distance are deduced. Finally, the influential factors of calculating space mean variance are analyzed combined with a static cone penetration data.
