（北京市建筑設(shè)計研究院，北京 100045）[摘要] 塞內(nèi)加爾國家劇院是一座能容納1800人的甲等特大型歌劇院，結(jié)構(gòu)體型復(fù)雜，內(nèi)部空曠、跨度大，防火要求高。擬建工程場址地層土質(zhì)分布極不均勻，荷載相差很大，根據(jù)工程場地的特殊性以兩種性質(zhì)孑然不同的土層作為聯(lián)合持力層，采用梁板式筏形基礎(chǔ)來調(diào)節(jié)基礎(chǔ)的不均勻沉降。通過地基基礎(chǔ)的協(xié)同分析，基礎(chǔ)的差異沉降滿足規(guī)范要求。劇場結(jié)構(gòu)中觀眾廳長懸挑梁和屋頂大跨度預(yù)應(yīng)力井字梁是結(jié)構(gòu)設(shè)計的難點，對此分別進行了介紹，相關(guān)經(jīng)驗可供類似工程參考。

( Beijing Institute of Arclutectural Design, Beijing 100045, China)Abstract: Senegal National Theater is an oversize opera house which can contain 1800 people, the theater characterize complex shape, hollow inside, long span and lugher fire resistance requirement. According to the special ground condition, the beam-slab raft foundation which based on two different soil layers was adopted, and the problem of stmctural unequal settlement was resolved effectively. The design of suspension beams of balcony in auditorium and long span prestressed cross-beams on proof were introduced respectively. The design experience can be referred in sinular engineering.
