摘要
土钉支护已在基坑和边坡中得到广泛的应用,土钉支护的内力和变形与其施工中"边支护边开挖"的特点是密不可分,常用的计算方法无法计算土钉支护坑壁的水平位移。针对土钉支护的施工特点,建立了考虑施工过程的土钉支护模型,并对施工阶段土钉支护上的坑壁水平位移进行了分析。在此基础之上,采用软件M atlab编写了有限元计算程序,并用大型有限元软件AD INA验证其结果,说明其正确性。
Soil nailed has been increasingly used in deep excavation and slope engineering because of its good mechanical and constructional performance. But only limited work has been done for the calculation of wall deformation during the construction. So it is necessary to investigate the horizontal displacement of the wall facing during its construction. Based on the theory of finite element, and using advanced programming language Maflab, the computation procedure is developed. In order to verify this procedure,nonlinear finite element(ADINA) is used to analysis this case. The comparative results show this method is credible.
