摘要
堆载预压法在路基工程中应用广泛,以二维比奥固结理论为基础,结合数值分析的方法对堆载预压法处理软土地基进行了数值模拟,研究了地基沉降和孔压的发展。结果表明:地基顶面路基中心线处的沉降最大,堆载方式对孔压曲线的形状具有很大影响;模拟结果合理,对于类似工程的设计和施工具有一定的参考意义。
Based on the two-dimensional Biot consolidation theory and combined with the numerical analysis method, this paper had numerical simulation of surcharge preloading method in soft soil foundation treatment, and studied the development of foundation settlement and pore pressure.
