［摘要］上海虹橋綜合交通樞紐是一項(xiàng)綜合性強(qiáng)、涉及面廣的系統(tǒng)工程，西航站樓、東交通中心、車庫(kù)、磁懸浮和地鐵隧道及車站等單體的施工在平面、時(shí)間和空間上相互重疊、縱橫交錯(cuò)。本工程基坑面積巨大、開挖深度超大、施工難度大，其基坑規(guī)模在上海地區(qū)乃至全國(guó)均屬罕見，而且工程工期十分緊迫。設(shè)計(jì)緊扣基坑面積巨大、挖深深、地下空間布置錯(cuò)落高低相連，周邊環(huán)境保護(hù)要求低等特點(diǎn)，經(jīng)過多種基坑支護(hù)設(shè)計(jì)方案的技術(shù)、經(jīng)濟(jì)和工期的綜合對(duì)比分析，最終采用多級(jí)梯次聯(lián)合支護(hù)體系的設(shè)計(jì)方案。該方案的應(yīng)用加快了基坑的施工速度，大幅度地節(jié)省了工程造價(jià)，取得了良好的社會(huì)和經(jīng)濟(jì)效益，為同類工程提供了一些借鑒。

Abstract: Shanghai Hongqiao Integrated Transport Hub consists of a series of structures including the west airport terminal, east transport center, parking garage, maglev train, metro tunnels and stations etc. These structures are inner-connected and overlap with one another in terms of space. Meanwhile, the total area of excavation is huge with considerable depth of excavation and difficult to construct. The scale of such a project is unprecedented not only in Shanghai, but also in China. The time limit of construction is urgent. An innovative multi-level supporting system is finally chosen for the group foundation pits, through thorough comparisons of a variety of plans on the technical and economical aspects. The supporting system can facilitate the fast implementation of the project and help to cut down total project cost greatly. It not only achieves desirable economical and social benefits, but also serves as a reference for future similar mega-projects.

Keywords: deep foundation pit excavation; multi-level supporting system; Hongqiao Integrated Transport Hub; supporting
