摘要
桩锚支护已在基坑和边坡中得到广泛的应用。桩锚支护的内力和变形与其施工中锚杆"边支护边开挖"的特点是密不可分的,常用的计算方法无法计算桩锚支护坑壁的水平位移。本文针对桩锚支护的施工特点,建立了考虑施工过程的桩锚支护模型,并对施工阶段作用在桩锚支护上的坑壁水平位移进行了分析。在此基础之上,采用高级编程语言M atlab编写相应的计算程序,与实测结果相对比,验证其结果,说明其正确性。
Anchor piles bracing structure construction has been increasingly used in deep excavation and slop engineering applications because of its good mechanical and constructional performance.But only limited work has been done for the calculation of the pile deformation during the construction.So it is necessary to investigate the horizontal displacement of the pile during its construction.Based on the theory of finite element,and using advanced programming language Matlab,computation procedure is developed.In order to verify this procedure,the measured value is used to analysis this case.The comparative results show this procedure is credible.
