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。 Combined with the three research examples, the theoretical analysis of strength effect in geotechnical structural analysis is introduced. It can be seen from the above examples that geotechnical structural analysis needs reasonable selection of strength theory; otherwise, wrong results may be obtained. Since the unified intensity theory can express or approximate the existing various intensity criteria by taking different values ​​of the parameter b therein, and theoretically define their upper and lower bounds. Therefore, in the geotechnical structural strength analysis, the unified strength theory has a good application prospect.
