岩土工程可靠度简化分析方法

simplified Analysis Methods of Reliability in Geotechnical Engineering

土是一种非常复杂的工程材料，土参数的变异性一般都比较大。本文扼要阐述了土的不确定性的三种离散源，并采用 Ｔａｙｌｏｒ法分析岩土工程的可靠度。本文方法较为简便，可以满足一般性岩土工程设计评价和风险决策。

Soil is a complex engineering material and the variability of its parameters is high. Geotechnical variability results from many desperate sources of uncertainties such as inherent variabliity, measurement error, and transfor- mation uncertainty. The reliability of some problems in geotechnical engineering is computed by means of Taylor's methods. The method is simple and can be applied for the design of engineering and decision of rish.
