倾斜砖石古塔纠偏方法研究

The analysis method applied to inclination-control for sloped ancient masonry pagodas

结合西安市万寿塔纠偏加固工程实例,研究了湿陷性黄土地基砖石古塔的倾斜灾害成因及纠偏方法,并利用有限元软件,对纠偏效果进行了验证,结果表明,不均匀沉降是湿陷性黄土地基砖石古塔建筑出现倾斜的主要成因;塔体倾斜后,其不稳定性显著增加;抽土迫降法对既有倾斜古塔的纠偏效果显著。

Combining with the inclination consolidation project of Wanshou Pagoda in Xi＇an City,the paper researches the reasons for the inclination disaster and inclination-control methods for the brick-stone pagodas with collapsible loess foundation,adopts the finite element software to prove the inclination control effect,and proves by the result that the uneven settlement is the main reason for the inclination of the ancient brickstone pagodas with collapsible loess foundation,and indicates its instability of the structure increases after the pagoda inclination and the forced settlement method with pumped soil has evident inclination control effect for existing inclined ancient pagodas.
