摘要
本文在目前滑坡研究中滑坡判据没有统一标准的前提下，提出了小变形条件下的统一滑坡判据，并讨论了在数值模拟时不同方法的精度问题及应力间断线上重要的一些性质。对有限变形时塑性应变或塑性应变率作为滑坡判据的可能性作了进一步的分析。最后，指出了目前滑坡研究中存在的最大缺陷及解决方法。
General slope sliding criteria under a small deformation dondition are proposed in this paper. Meanwhile, the accuracy of different numerical methods and the important features of stress discontinuous line are discussed . The possibility of plastic strain and plastic strain rate for finite deformation considered as slope sliding criteria is studied further. Finally the conspicuous defects in present slope stability theory are pointed out, and the correct direction and its solution methods are suggested.
