摘要
根据武广高速铁路软土地基沉降的实际测量数据,研究软土地基沉降的竖向、侧向位移及超静孔隙水压力随时间变化的一般规律,采用非线性分析软件ADINA建立路基土体固结沉降的有限元模型,并将有限元计算结果与实测数据相比较,吻合程度较高,并说明了存在少许差异的原因。
According to the measured data about soft foundation settlement of Wuhan-Guangzhou High-speed Railway, the general law of vertical and lateral displacement of soft foundation settlement and excess pore water pressure changing over time is studied. The finite element model of subgrade soil consolidation settlement has been established using nonlinear software ADINA. data, which are highly consistent with each other. Then the finite element result is compared Finally, the reason for the little difference with the actual is described.
