摘　　要：以某建筑深基坑工程为例,对基坑开挖各阶段上部土钉墙土钉轴力进行实测,分析并研究了基坑开挖及支护过程对土钉轴力的影响,具体考虑了基坑开挖时间与土钉轴力、土钉轴力变化速率以及同一土钉不同节点位置处轴力变化趋势之间的关系。对今后类似的基坑工程中的上部土钉墙的设计和分析提供借鉴和参考。With a deep foundation pit engineering an example,for each stage of excavation,the soil nail axial force of upper soil nail wall is monitored. The effect of the process of foundation pit excavation and support on soil nails axial force is analysed and studied,specially,the relationship between excavation time and axis-force of soil nailing,changing rate of axisforce,as well as changing trend of axial force in different positions with the same soil nail,is considered. It can provide a reference for the design and analysis of top soil-nailed wall in those similar foundation pit engineerings.
