| 摘 要： | 在淤泥上填筑围堰,可应用砂被塑排法固结增强软土,而堤身的大变形与填筑过程中的稳定性是其地基处理的关键。结合工程实例,利用PLAXIS有限元软件对围堰的填筑过程进行模拟,分析了地基土的固结变形、超孔压消散与稳定性,并通过方案对比得出了不同边界范围、加载方案、是否考虑砂被加筋作用对数值计算的影响。

| Abstract: | Consolidation settlement and slope stabilization are major concerns during construction of
cofferdam on soft soil with plastic drainage plate and sand bedding. PLAXIS is used to simulate the layered buried
progress of some cofferdam to analyze deformation, excess pore pressure dissipation and stabilization. Then the
effects of bounds, loading scheme and reinforcement on results are concluded by contrasting. |
