［摘要］在萬銀國(guó)際大廈基礎(chǔ)設(shè)計(jì)中，主樓部分采用基礎(chǔ)變剛度調(diào)平設(shè)計(jì)原則，對(duì)樁和筏板進(jìn)行了優(yōu)化設(shè)計(jì)，對(duì)樁的持力層和類型進(jìn)行了合理選擇。分析了后注漿對(duì)持力層壓縮模量等物理性能及樁剛度的改變。采用JCCAD軟件對(duì)主樓與裙房基礎(chǔ)間差異沉降進(jìn)行計(jì)算，與現(xiàn)場(chǎng)沉降觀測(cè)結(jié)果進(jìn)行了對(duì)比。

Abstract:In the foundation design of Wanyin International Mansion, adjusted foundation rigidity design was adopted for reducing different settlement, and optimum design for piles and raft plates was used. Supporting course and type of piles were selected. Transformation of compressive modulus and pile-stiffness by post grouting was analyzed. Different settlement of main building and the podium was calculated by JCCAD and field measurement result was compared.

Keywords:pile-raft foundation; post grouting; compressive modulus; different settlement
