大瑶山一号隧道开挖变形分析

The excavation deformation analysis of Dayao mountain first tunnel

以大瑶山一号隧道为主要研究对象,大型非线性有限元软件ADINA为研究工具,建立有限元模型,得出模拟值与实际监测变形值相差不大,通过对提取后处理变形数据进行分析得出了规律,并根据得出规律提出了应对措施。

The subject investigated of this paper is the foundation pit of Dayao mountain first tunnel, the research instrument is nonlinearity finite element software which is called ADINA. Established finite element model, simulated value and practice value has small difference, through extracting and analyzing aftertreatment transformation data elicit some law, and put forward relevant measures.
