摘　　要：为分析装配式钢支撑在南京江宁地区的有效性和可靠性,以江宁区竹山路附近的某深基坑工程为例,介绍了装配式H型钢支撑的布置形式和设计计算要点,并对比了基坑位移的理论计算值与实测值,结果表明:理论计算的侧向位移与同部位深层水平位移实测数据接近,变形规律基本一致,证实了装配式H型钢支撑在该地区用于基坑支护的有效性。In order to analyze the effectiveness and reliability of prefabricated steel bracing in Jiangning area of Nanjing,taking a deep foundation pit project near Zhushan road in Jiangning District as an example,the layout form and design calculation points of prefabricated H-shaped steel support are introduced,and the theoretical calculation value and measured value of foundation pit displacement are compared.The results show that the theoretical calculation of lateral displacement and the field measured deep horizontal displacement of soil are both near to eachother the deformation rule is the same.The results show that the assembled H-beam support is effective for foundation pit support in this area.
