（福建省建筑設(shè)計(jì)研究院 福州 350001）[提要] 以福州銀河大廈工程為實(shí)例，闡述了在復(fù)雜條件下高層建筑軟土深坑支護(hù)結(jié)構(gòu)的設(shè)計(jì)與實(shí)踐，提出對這一類支護(hù)結(jié)構(gòu)方案除按常規(guī)設(shè)計(jì)外，還需依據(jù)工程的特殊條件，對工程的薄弱環(huán)節(jié)進(jìn)行評估、補(bǔ)充設(shè)計(jì)與監(jiān)測，以確保工程安全可靠。

Except for macroscopic routine design, the week link of the project must be evaluated, and additional design and measurement must be done according to the special condition of the project to guarantee the softy and reliability of the project.
Keywords: bracing structure; foundation pit; excavation pile; steel pipe support; finite element analysis; elastic-support; high pressure; jet grouting
