樁+內(nèi)支撐支護(hù)體系在武漢某深基坑工程中的應(yīng)用
摘 要:該文概述武漢某基坑在環(huán)境條件復(fù)雜、開挖深度達(dá)17 m的條件下,采用排樁+2道內(nèi)支撐支護(hù)體系的基坑設(shè)計(jì)方案。通過分析、比較計(jì)算結(jié)果及監(jiān)測(cè)數(shù)據(jù),該支護(hù)體系有效地控制周邊沉降及位移,確保周圍建筑物的安全,可為類似工程的設(shè)計(jì)與施工提供借鑒。
關(guān)鍵詞:基坑支護(hù);排樁;內(nèi)支撐;復(fù)雜環(huán)境;監(jiān)測(cè)

Abstract: This paper summarizes the design scheme of a foundation pit in Wuhan with row piles + 2 internal support system under the condition of complex environmental conditions and excavation depth of 17 meters. By analyzing and comparing the calculation results and monitoring data, the support system effectively controls the surrounding settlement and displacement, ensures the safety of the surrounding buildings, and can provide reference for the design and construction of similar projects.
Keywords: foundation pit support; row piles; internal support; complex environment; monitoring
隨著城市建設(shè)的快速發(fā)展,建筑物密度日益增大, 擬建工程周邊都存在著交通道路、建筑物及地下管線, 對(duì)變形控制日趨嚴(yán)格[1-2],加之國(guó)內(nèi)很多城市都限制紅線外使用錨桿(索),使得基坑開挖場(chǎng)地愈加狹小,樁+內(nèi)支撐支護(hù)結(jié)構(gòu)形式逐漸成為深大基坑支護(hù)設(shè)計(jì)中首選形式之一[3]。(剩余6081字)
