在经典连续介质弹塑性理论框架下，结合岩土工程应用背景，总结和论述了岩土材料复杂应力状态下强度理论的发展状况，指出岩土强度理论是水利、土木、矿业、铁道等工程中结构件设计和强度计算必要的基础理论，因此强度理论得到广泛的研究和应用。%Under the classical continuum elastic-plastic theory, combining with the geotechnical engineering application prospect, this paper summarized and discussed the development situation of strength theory under geotechnical materials complex stress, pointed out that the rock and soil strength theory was the necessary basic theory of structure design and strength calculation of water, civil engineering, mining, railway and other engineering, so that the strength theory gained widely research and application.
