| 摘 要： | 文章研究不同悬臂桩支护的间距布置对悬臂桩支护性能的影响．通过在实验室条件下的数据采集仪与位移计等设备将实验所采集到的悬臂桩支护模型下基坑的实时位移变形数据输入到计算机，并利用自行研发的基坑工程可视化监测系统3DVMS（3DVisualizedMonitoringSystem），对基坑全模型进行了实时监测，实现了实时预警功能．实验与数值分析结果表明，在实验范围内，悬臂桩对基坑的支护性能随间距的减小而增强，在间距为40mm时支护效果最佳．

| Abstract: | In this paper, it is studied how the spacing layout of the pile bracing affects the retaining perform- ance. Collected from the displacement gauge and other equipment in the laboratory, the real-time data of the displacement and deformation of the foundation pit based on pile bracing system are input into computer, and all models of the foundation pit are monitored in real time by using a 3DVMS （3D Visualized Monitoring System）. Experiment and numerical analysis results show that： in the experimental range specified in this paper, the sup- porting pile＇s performance strengthens with the decrease of the spacing, and reaches its best effect when the spacing is about 40 mm. |
