摘要
结合湿陷性黄土地基的特点,对陕西眉县净光寺塔纠偏工程进行了有限元模拟。以地基土性参数的改变模拟注水对地基土的影响,分析了采用该法纠偏砖石古塔过程中地基、结构的受力及变形特点,并将计算纠偏结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,采用"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 region, the rectification construction of the Jingguang Pagoda in Meixian County, Shaanxi Province is simulated by finite element method. With the changes of soil parameter, the influence of injecting water on subsoil is simulated and the characters of soil and structure of the tower during rectification are analyzed. At the same time, the result of calculation is contrasted to that of the test and some 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 rectification method in collapsible loess region.
