| 中文摘要:为保证监测质量，为信息化施工和优化设计提供依据，深层土体水平位移的监测在基坑开挖中至关重要。以浙江省玉环县城中村改造安置房(17号小区地块)工程施工监测为例，论述了该工程的深层土体水平位移动态变化，介绍了新规范与实际操作中监测频率和监测警报值等内容。监测表明：基坑开挖过程中深层土体位移角度，主要发生在孔口及以下3 m内；基坑周围土体水平位移基本在安全范围内，且最终趋于稳定。通过分析研究基坑监测结果，对施工进行信息反馈，有效地保证了基坑的安全。 |

| Abstract:The monitoring of the deep soil horizontal displacements is very important in the excavation process. Based on the monitoring on the deep soil horizontal displacement in Yuhuan, the paper discussed the dynamic change of the displacement. The monitoring result shows that deep soil horizontal displacement usually happened near the orifice or 3 m below it; soil horizontal displacement situation of each hole was in safety range and tended to be stable. The foundation pit was effectively guaranteed by the information feedback to the construction according to the analysis study on the foundation pit monitoring effect. |
