[摘要] 以徐州老城區(qū)周邊復(fù)雜環(huán)境下的深基坑為背景，對淺錨+支護(hù)樁+內(nèi)支撐這種組合支護(hù)方式進(jìn)行了研究。分析了上述支護(hù)方式下支撐軸力、圍土位移、樁頂沉降和坑內(nèi)降水等監(jiān)測數(shù)值的分布規(guī)律，結(jié)果表明，基坑各項監(jiān)測指標(biāo)均在設(shè)計允控范圍內(nèi)，支護(hù)方式的合理性可保證此地質(zhì)和環(huán)境下的正常施工。為徐州地區(qū)類似地質(zhì)和周邊環(huán)境下的基坑支護(hù)設(shè)計與施工提供一定的參考。

Abstract: Background of deep foundation pit in the old city complex environment of Xuzhou, shallow anchor +retaining pile+ internal bracing this composite support were studied. Distribution of supporting forces, soil displacement, pile top settlement, and dewatering monitoring data with these support method are analyzed, the results showed that the pit monitoring indicators in design allowable range, supporting reasonable assurance the normal construction under this geological and environmental, and providing some reference of foundation pit support design and construction about similar geology and around environments in Xuzhou.
Keywords: deep foundation pit; construction monitoring;
