[摘要]超高層建筑地下工程造價高、工期長,與業(yè)主加快資金周轉(zhuǎn)速度的需求之間矛盾突出,不同類型的逆作法逐漸成為縮短地下工程工期的首選。結(jié)合不同地質(zhì)條件下的若干實(shí)際工程,對地下工程施工方案進(jìn)行了綜合對比分析,并對全逆作法、逆作正挖法及部分逆作法的設(shè)計關(guān)鍵技術(shù)及施工要點(diǎn)進(jìn)行了闡述。對不同場地條件下逆作方案的選擇提出了建議。

Abstract:The underground engineering of super highrise buildings has high cost and long construction period, which comes into conflict with the owners demand of accelerating the capital turnover rate. Various types of top-down construction methods gradually develop into the first choice to reduce the construction period of underground engineering. Combined with some practical projects in different geological conditions, comprehensive comparisons for underground engineering schemes were made, and the key points in design and construction stage of topdown construction, topdown construction with inverse excavation and partial topdown construction were introduced. Some suggestions for topdown construction scheme in different site conditions were given as references.
Keywords:super high\|rise building; topdown construction method; barrette; Tianjin R&F center; Harbin Jiangwan new town; Guangzhou Yingkai plaza
