强度理论效应对岩土工程结构分析的影响

INFLUENCES OF THE STRENGTH THEORY ON GEOTECHNICAL STRUCTURE ANALYSIS

结合三个研究实例,对岩土工程结构分析中的强度理论效应做了分析介绍。从上述实例中可以看出,岩土工程结构分析需要对强度理论进行合理选用;否则,就有可能得出错误的结果。由于统一强度理论可以通过对其中的参数b取不同值来表达或近似表达现有的各种强度准则,并且从理论上界定了它们的上限和下限。因此,在岩土工程结构强度分析中,统一强度理论具有较好的应用前景。

Influences of strength theory on the analysis ofgeotechnical structures is introduced with three typical examples, in which we can realize that the selection of a available material failure criterion is very important for the structural analysis. The unified strength theory encompasses all the other theories as its special cases or approximation, and the theories of lower and upper bounds has been given through the changing of parameter b. So the unified strength theory will be used in the structural analyses in future.
