摘要
为深入了解土体强度折减法所存在的问题,对土体强度折减法的提出、发展和应用进行系统的研究和总结。分类概述了强度折减法的理论概念、边坡破坏面的位置和方向以及基于强度折减法数值分析等方面的研究进展及存在的问题,重点对强度折减法用于分析成层土及带有结构物边坡的合理性、边坡失稳判据和安全系数等三个方面存在的不足进行评述,并对其进一步的研究和应用提出了建议。
In order to make a deep understanding of the existing problems about strength reduction method, the proposal, development and use of the strength reduction method were studied and summarized. Several aspects of the research progress and problems including the theoretical concepts, the position and orientation of failure plane of slopes and the numerical analysis method based on strength reduction were overviewed. The deficiencies in the rationality of the strength reduction method used to analyze layered soil and slope with structures, the slope failure criterion and influence factors of safety factor were emphatically commented. Some suggestions on further study of strength reduction method and its application were proposed.
