基于可拓理论的边坡地震稳定性评价方法研究

针对影响边坡稳定性因素的不确定性和错综复杂性以及传统分析方法的主观性和不切实际性，本文提出了一种基于可拓理论的多层次多指标的综合评价方法，并对辽宁省的庄河边坡从地质条件、环境条件和工程条件三个层次五个指标进行了稳定性评价，确定了该边坡的稳定性等级，研究了影响该边坡稳定性的因素。同时，通过计算各影响因素的可拓关联度、权重等指标，得出了地震力是影响该边坡稳定性的最重要指标。在此基础上，从库伦强度理论和岩体应力状态两个方面，分析了竖向地震力和水平地震力对边坡稳定性的影响。该方法将可拓理论和地震力对边坡稳定性的影响相结合，不仅为边坡稳定性分析提供了一种综合的研究方法，而且为采取有针对性的加固措施提供了可靠的依据。

Evaluation method of seismic slope stability based on extension theory

With the uncertainty and complexity of influence factors and the subjectivity and impracticality of traditional methods, a comprehensive evaluation method based on extension theory was studied. The stability of Zhuanghe slope in Liaoning Province was evaluated from the geological conditions, environmental conditions and engineering conditions. At the same time, the level of the slope stability was determined and the factors influencing the slope stability was studied. By calculating the extensible correlation, weight and other indicators of influence factors, the seismic force is the most important index for slope stability. On this basis, the effects of horizontal and vertical seismic force on slope stability were studied from the Coulomb strength theory and the stress state of rock. This method combine the extension theory with the impact of seismic force on slope stability, which not only provides a comprehensive methods for analyzing the slope stability, but also provides a reliable basis for taking targeted reinforcement measures.
