摘　　要：根据岩石力学实验方法,建立了混沌动力学评价砂岩节理裂隙系统稳定性的TDS准则,构建出砂岩裂隙系统的LE1-m关系TDS准则数学模型,在一定程度上克服了混沌动力学评价指标传统确定方法的局限、即Wolf方法鲁棒性较差的问题,对混沌动力学理论的更好应用具有实际意义.With dynamical method of chaos, the TDS criterion based on rock mechanical tests to value stability of sandstone joint system was constructed. Mathematical model of TDS criterion from the relationship of LE1 and m for sandstone joint system was obtained. The TDS criterion to determine chaotic indexes can eliminate the limitation of Wolf＇s method whose robustness was not high and so is of vital significance to the chaotic theory.
