摘要
借助室内试验、可靠度分析和有限元技术,采用Duncan-Chang非线性本构关系,建立了土性参数随机场模型,对深汕西高速公路浸水路段路基的稳定性进行了评估。评估得出的结论与现场监测反馈的结果相一致,从而证实了采用非线性摄动随机有限元法评估浸水路段路基稳定性可靠度是可行的,可供今后类似的工程处理提供借鉴。
In this paper, the stability of soaked roadbed in western section of Shenzhen to Shantou highway is evaluated, which is based on lab tests, reliability analysis and Finite element technology and the DuncanChang non - linear constructive relation is applied to build random field model. The result fed back from the site monitoring agree with the evaluation, which has proved that it is feasible to evaluate reliability of the soaked roadbed stability by the nonlinear perturbation random finite element method. Therefore, the method can provide technical guidance for future works in this field.
