岩土工程中随机—模糊统计公式的修订及应用

Amendment of random-fussy statistical formulation in geotechincal engineering and application

岩土工程中的随机—模糊统计方法用模糊理论准确表达了岩土材料特性的空间变异性,通过信息理论、计算技术与岩土力学的结合,实现了模糊模型的定量求解并使经典的随机统计公式作为一种特例包含于相应的随机—模糊统计公式中。简述了岩土工程中随机—模糊统计原理和相关计算公式,并对这些计算公式进行了局部修订以完善其理论逻辑,讨论了应用岩土工程中随机—模糊统计原理和相关计算公式应注意的问题以便推广应用。

The random-fuzzy statistical principle and relative computation formulae used in geotechnical engineering expresses spatial variability of geotechnical material,through combination of information theory,computation technology and geotechnical mechanics,quantitative computation of fuzzy model is realized and classical random statistical formulae is included in correspondent random-fuzzy statistical formulae as a special case.This paper briefly describes the random-fuzzy statistical principle and relative computation formulae and partially revised the formulae to perfect theoretic logic,discusses the problems to be pay attention while application of the random-fuzzy statistical principle and relative computation formulae in geotechnical engineering to facilitate popularization and application.
