| 摘 要： | 基于Biot固结理论和强度折减思想,利用快速拉格朗日差分法,对高速公路路基沉降和稳定性进行实时同步数值分析。结果表明,施工期随着填筑高度的增加,地基沉降呈线性增大,路基边坡的安全系数逐渐减小;道路营运期,随着孔隙水压的消散,固结沉降累积最终趋于稳定,边坡的安全系数在施工完毕初期为最小。

| Abstract: | Based on Biot consolidation theory and strength reduction concept,using rapid Lagrange method of difference,this paper carries out real-time synchronous numerical analysis on expressway subgrade settlement and stability.The result shows that during construction period,with the increase of filling height,subgrade settlement increases linearly and slope safety factor decreases gradually.During operation period,with the diffusion of pore water pressure,cumulative consolidation settlement finally trends stable.... |
