摘要
将强度折减原理与ABAQUS软件相结合,对边坡失稳判据进行了分析,认为位移突变和塑性区贯通判据有明确的物理意义.通过算例分析,并于bishop法所得到的安全系数进行对比.结果表明,采用位移突变和塑性区贯通作为失稳判据所得到的安全系数是合理可靠的.
The slope off-balance basis is newly analyzed based on strength decreasing principle and ABAQUS software, paying more attention to the physical performances including the judgment of displacement mutation and plastic zone breakthrough, the security index of which is illustrated to be reliable compared with the security index of bishop algorithm.
