| 中文摘要:分层标是通过钻探方法分别埋设在地下不同深度土层中的特殊监测点，标点直通地表，随土层的压缩、膨胀而升降变化，由此监测地面的总沉降量或总回弹量。通过温州市地面沉降监测标组的施工实践，探讨了确保分层标质量的关键工序和控制措施，并对标底装置作了技术改进。分层标的建设可为该地区今后地面沉降防治、地下水资源合理开发利用提供更有效的基础资料和决策依据。 |

| Abstract:Layerwise mark is formed of special monitoring points buried in soil layers of different depth by drilling and exposes on the earth's surface; Based on the variation coming along with the compression and expansion of soil layers, the total settlement and resilience amount of the ground can be monitored. With the construction practice of subsidence monitoring marks in Wenzhou, the key working procedure and control measures for ensuring the quality of layerwise mark are discussed with the improvement of the basement device. |
