［摘要］為了解決緊貼既有建筑物限制、施工條件限制、地質(zhì)條件差等困難，西樵紡織科技大廈基坑支護工程采用了地下連續(xù)墻+半逆作法內(nèi)支撐方案，該方案具有安全可靠、施工較方便、節(jié)約工期、經(jīng)濟性較好、環(huán)保性好等優(yōu)點，且多處體現(xiàn)了“一種結(jié)構(gòu)，多種用途”的巧妙設(shè)計?；又ёo工程及地下室施工期間，未發(fā)現(xiàn)地面明顯開裂和下沉，未出現(xiàn)地下室市政管線遭遇破壞情況，緊貼的既有建筑未發(fā)生新增裂縫或下沉現(xiàn)象，達到了預期的支護效果，可供同類工程參考。

Abstract:In order to solve the difficulties of existing building restrictions, construction conditions restrictions and geological conditions, the scheme of underground diaphragm wall + internal strut of semi-reserved construction method in retaining and protection for foundation pit was applied in the construction project of Xiqiao Textile Technology Building. This scheme has the advantages of safe and reliable, convenient construction, saving construction period, good economy and good environmental protection. Moreover, retaining and protection for foundation pit reflects the ingenious design of “one structure, multiple uses” in many ways. During the period of foundation pit support engineering and basement construction, no obvious ground cracking and subsidence were found, no basement municipal pipeline was damaged, and no new cracks or subsidence occurred in the existing adjacent buildings. The foundation pit support achieved the expected effect and the design experience could be used as reference for similar projects.
Keywords:retaining and protection for foundation pit; diaphragm wall; internal strut; semi-reserved construction method
