摘要： 结合某基坑工程监测实践，对坡顶水平位移及垂直位移、土体深层水平位移、桩（柱）内力、锚杆（索）内力等项目进行监测，对土体深层水平位移和桩板深层水平位移的变化趋势及原因进行分析，对部分测点超出报警值，应采取相应报警措施，综合分析、判断保证基坑安全稳定性。

Abstract: This paper presents a case history of the monitoring results of a deep excavation.  The monitored data include: horizontal and vertical displacement at the ground surface near the excavation; various ground settlement below the excavated soils; internal forces within the supporting sheet piles and well as ground anchors. This paper discusses and analyzes the monitored soil as well as sheet pile displacements. The excessive deformations at several locations were consequently analyzed and the safe excavation was ensured.

Key words: Deep Excavation Monitoring, Horizontal Displacement, Monitoring and Analysis, Excavation Stability
