[摘要]  以徐州老城区周边复杂环境下的深基坑为背景，对浅锚+支护桩+内支撑这种组合支护方式进行了研究。分析了上述支护方式下支撑轴力、围土位移、桩顶沉降和坑内降水等监测数值的分布规律，结果表明，基坑各项监测指标均在设计允控范围内，支护方式的合理性可保证此地质和环境下的正常施工。为徐州地区类似地质和周边环境下的基坑支护设计与施工提供一定的参考。

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; Xuzhou old city
