| 中文摘要: |
| 中国南部地区特别容易发生滑坡事故，主要由于表土风化和强降雨引发，对矿业生产带来不良影响。因此，急需采取有效监测和预警措施。近年来，合成孔径雷达技术迅速发展，并已应用于替代GNSS对矿山边坡进行表面位移监测。本研究以珠江水泥石灰石矿山为例，验证了在强风化长雨季条件下，GNSS与合成孔径雷达技术在矿山边坡监测方面的适用性。对比分析结果显示：两者记录的边坡位移变形趋势一致，为滑坡演化提供了关键信息；然而，GNSS需要更密集的本地观测网络以提供更准确的位移评估和滑坡风险控制；合成孔径雷达技术在特殊气象和地理环境下的应用需要特定的处理工具进行一定程度的校正。 |
| 英文摘要: |
| The southern regions are prone to mountain landslides， primarily due to loose soil and heavy rainfall， which adversely affect mining activities. Therefore， there is an urgent need for effective monitoring and warning measures. In recent years， synthetic aperture radar （InSAR） technology has rapidly developed and has been applied to replace GNSS for surface displacement monitoring of mine slopes. This study， using the Zhujiang cement limestone mine as an example， validates the applicability of GNSS and InSAR technology in monitoring mine slopes under conditions of intense weathering and prolonged heavy rainfall. Comparative analysis results show that both methods record consistent trends in slope displacement， providing crucial information for landslide evolution. However， GNSS requires a denser local observation network for more accurate displacement assessment and landslide risk control. The application of InSAR technology in specific meteorological and geographical conditions requires certain levels of correction using specific processing tools. |
