摘要
结合湿陷性黄土地区地基特点,对陕西省眉县净光寺唐塔纠偏工程中采用的"成孔-软化"法进行了有限元模拟.以地基土参数的改变来模拟注水对地基变形的影响,分析了古塔纠偏过程中地基、结构的受力及变形特点,同时将计算纠偏效果与实测纠偏效果进行对比分析,依据计算结果提出了纠偏施工中的相关建议.结果表明:采取相应的加固措施,"成孔-软化"纠偏方法可确保纠偏过程中古塔结构的安全性以及纠偏实施效果,为湿陷性黄土地区一种行之有效的纠偏方法.
In light of characters of soil in collapsible loess reign, the rectification construction of the Jingguang Pagoda in Meixian County Shaanxi Province, which was built in Tang Dynasty,is simulated d by finite element method. By changes of parameters of soil, the influence to subsoil of injecting water is simulated and the characters of soil and structure of the tower during rectification are analyzed. And the results of calculation are contrasted to that of the test and some relatived suggestions are brought out. As a result, some strengthen measures adopted, the rectification method of holes drilling and soften can ensure the safety of the structure and effect of rectification of masonry pagoda. That is an effective rectifi cation method in collapsible loess region.
