［摘要］本工程為坡地建筑，南北兩側(cè)地坪高差15m左右，為了抵抗較大的土側(cè)壓力，整個(gè)結(jié)構(gòu)為不設(shè)縫的大底盤六塔結(jié)構(gòu)。結(jié)構(gòu)的分析和設(shè)計(jì)分整體計(jì)算和分塔計(jì)算，整體計(jì)算介紹了整體模型的建立，將其計(jì)算結(jié)果與單塔模型的計(jì)算結(jié)果進(jìn)行了對(duì)比，分析了塔樓與大底盤的相互影響；分塔計(jì)算采用SATWE與PMSAP對(duì)塔樓進(jìn)行了彈性比較分析，還進(jìn)行了彈性動(dòng)力時(shí)程分析和中震不屈服分析。對(duì)超長(zhǎng)結(jié)構(gòu)采取了一定的措施以抵抗混凝土的溫度和收縮應(yīng)力。建議在類似工程的結(jié)構(gòu)設(shè)計(jì)時(shí)，應(yīng)采取可靠措施防止后澆帶封閉之前結(jié)構(gòu)在土側(cè)壓力作用下發(fā)生傾覆和滑移。

Abstract: This project lands on slope field, of which ground level difference between north side and south side is about 15 meters. To resist the lateral soil pressure, six-tower structure was applied with large podium without expansion joints. Analysis and design of the structure were divided into total analysis and analysis by tower. Total modeling and interaction effects between towers and large podium were introduced in total analysis. Besides, the calculation results of total modeling were compared with that of single tower model. Elastic comparative analysis was carried out by SATWE and PMSAP programs in analysis by tower as well as elastic dynamic time-history analysis and non-yielding analysis under intermediate earthquake. Some measures were taken in super-long structure to resist temperature stress and contraction stress. It is recommended to take reliable measures to prevent structural overturn and slippage due to lateral soil pressure before post-pouring joint is finished.

Keywords: structure with large podium; RC frame-corewall structure; interaction effect between towers and large podium; super-long concrete structure
