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 understand deeply the existing problems of soil strength reduction method, this paper systematically studies and summarizes the proposal, development and application of soil strength reduction method. The paper summarizes the theoretical concept of strength reduction method, the position and direction of failure surface of slope, and the research progress and existing problems in numerical analysis based on strength reduction method. The emphasis is on the application of strength reduction method in analyzing layered soils and structures The rationality of object slope, the criterion of slope instability and the safety factor, and gives some suggestions for its further research and application.
