    摘要:

    探地雷达具有便捷、高分辨率等优点,为避免某接收沉井在下沉过程引起地面塌陷灾害,采用探地雷达对沉井施工引起的地面沉降区进行探测,查明沉井施工可能影响的沉降范围及地层脱空情况。通过在介绍探地雷达基本方法原理的基础上,结合温州市瓯江路接收沉井的工程地质资料和雷达检测数据,判断可能发生地质灾害类型、范围。实践证明探地雷达可以准确定位地面沉降范围、分辨不密实体以及地层脱空等地质灾害,为工程采取有针对性的安全措施提供指导作用。

    Abstract:

    Ground penetrating radar has advantages such as convenience and high resolution. In order to avoid ground subsidence caused by sinking of a receiving caisson, ground penetrating radar is used to detect the ground subsidence area caused by caisson construction, and the settlement range and formation voiding that may be affected by caisson construction are identified. Based on the introduction of the basic method of ground penetrating radar, combined with the engineering geological data and radar detection data of sinking wells in Oujiang Road, Wenzhou City, the types and scope of possible geological disasters are determined. Practice has proved that ground penetrating radar can accurately locate geological disasters such as ground subsidence range, distinguish between dense entities, and underground evacuations, and can provide guidance for engineering to take targeted safety measures.
