摘要
对工程实例的路基横向滑移破坏,首先采用极限平衡理论确定边坡滑动的最危险滑动面,将可靠度理论与有限元强度折减法相结合,在考虑土体的弹塑性本构关系和塑性应变的情况下,对路基滑移安全系数、强度折减系数和可靠度指标进行耦合分析,阐述边坡失稳定机理,为工程治理提供可靠依据。
The most dangerous sliding surface slope slide is determined by the limit equilibrium theory,when the subgrade of the project is destroyed.The subgrade safety coefficient,the sliding strength reduction coefficient and the reliability indexes are coupled to analyze,and the soil elastoplastic constitutive relation and the plastic strain are considered.The paper provides reliable basis for project management through elaborating the slope unstability mechanism.
