(建學(xué)建筑與工程設(shè)計(jì)所有限公司上海分公司，上海200336)[摘要] 法門寺合十舍利塔位于陜西省寶雞市扶風(fēng)縣，屬復(fù)雜混合結(jié)構(gòu)的超限高層，其主體塔基底下為無濕陷性土層，裙樓地基屬III級濕陷性黃土。主塔采用大直徑鉆孔灌注樁，樁端及樁側(cè)后注漿，并先期對試樁采用自平衡檢測技術(shù)。根據(jù)專家提議進(jìn)行優(yōu)化，考慮樁承載力效率及變剛度調(diào)平思想，選用略高于規(guī)范限值的樁身強(qiáng)度并取得了良好的效果。底板設(shè)計(jì)主要遵循了“地盡其力，就近分配”的原則。

(Jianxue Architecture and Engineering Design Institute Co., Ltd., Shanghai branch, Shanghai 200336, China)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
