[摘要] 法门寺合十舍利塔位于陕西省宝鸡市扶风县，属复杂混合结构的超限高层，其主体塔基底下为无湿陷性土层，裙楼地基属III级湿陷性黄土。主塔采用大直径钻孔灌注桩，桩端及桩侧后注浆，并先期对试桩采用自平衡检测技术。根据专家提议进行优化，考虑桩承载力效率及变刚度调平思想，选用略高于规范限值的桩身强度并取得了良好的效果。底板设计主要遵循了“地尽其力，就近分配”的原则。

Abstract: The Buddha Relics Tower of Famen Temple is located in Fufeng County, Baoji City of Shaanxi Province. It is a super-tall complicated mixed structure, with non-collapsible soil under the main Tower, and grade III collapsible loess under the skirt rooms. Large diameter bore piles are used under the main Tower, and post pressure grouting is used in the terminal and pile sides after self-balance technology on 3 test piles. Bearing strength little higher than code specifications have been used according to experts' suggestion including pile capacity efFiciency and pile foundation stiffness to reduce differential settlement. Basement design follows the principle of "utilizing to the utmost the soil capacity with distribution to its adjacent".
Keywords: collapsible loess; post pressure grouting; self-balance method; bored pile; earth pile
