| 摘 要： | 运用大型非线性有限元软件ADINA,模拟某深基坑土钉+水泥土搅拌桩复合土钉墙基坑开挖与支护的施工过程,建立了整体三维有限元模型,模型考虑了基坑的整体空间作用,克服了二维平面或局部的三维有限元模型分析的不足.分别得出了基坑的整体位移、开挖面的水平位移、坑后地面沉降的位移、坑底隆起的位移,并与现场实测值进行了对比.结果表明,计算值与实测值基本吻合,说明建立的非线性有限元计算模型和分析方法是可靠的,能够较好地运用于实际工程的分析和预测.

| Abstract: | Based on the nonlinear finite element software ADINA,the construction process of excavation and supporting of the composite soil nailed wall of soil nailing and cement-soil piles for deep foundation excavation is simulated by a whole three-dimensional finite element model.Spatial action of foundation pit was considered in the model.The deficiencies of two-dimensional plane model or a partial spatial one were overcomed.Whole displacement of foundation,the horizontal displacement of excavation face,the subsid... |
