| 摘 要： | 从理论分析着手,建立路基沉降变形控制系统模型。根据室内试验成果,对路基沉降进行数值分析。模拟不同参数对沉降的影响,研究不同工况中路基沉降的控制效果。地基弹性模量对沉降影响大,提高地基弹性模量,沉降将减小,并且减小的幅度很大;填料密度对沉降影响较大,降低填料密度,沉降将减小,并且减小的幅度很大;路基累积沉降量与路基本体高度之间存在近似线性正相关关系;路基累积沉降量与地基处理深度之间存在近似线性负相关关系。

| Abstract: | From the beginning of theory analysis,this paper establish control model of embankment settlement deformation.According conclusion of Lab to simulate embankment settlement,and analysis the control effect of different work.Main conclusion is:increase foundation elastic modulus can decrease settlement;decrease fills density can decrease settlement.Embankment settlement is nearly positive correlation to embankment body height;embankment settlement is nearly negative correlation to foundation treat depth. |
