| 中文摘要: |
| 2018年8月9日，兰州北环路发生山体滑坡，滑动体积约有66 × 104m3。滑坡体造成北环路双向车道被掩埋，交通中断，严重影响了兰州市民的安全出行，当地政府采取削坡减灾等措施对滑坡实施了应急治理。为保障车辆安全通行提供决策依据，对滑坡开展了地基InSAR监测工作。本文在现场调查的基础上，以R／HYB 1000型地基雷达系统作为监测工具，开展了针对滑坡应急治理后的效果监测，通过地基雷达获得滑坡地表监测数据并结合宏观调查，对滑坡应急治理后的稳定性进行了分析，为滑坡治理和道路恢复通行提供了科学依据。同时，也验证了地基雷达在黄土裸露区的应用效果，为甘肃滑坡应急监测技术推广应用提供了依据。 |

| On August 9, 2018, a landslide occurred in Beihuan Road, Lanzhou, with a sliding volume of 66×104m3. The landslide buried the bidirectional lanes of the north ring Road and interrupted traffic, seriously affecting the safety of lanzhou citizens. The local government took measures such as slope cutting and load reduction to implement emergency treatment of the landslide. In order to guarantee the safe passage of vehicles, ground-based InSAR monitoring was carried out. In this paper, on the basis of field investigation, in order to
R／HYB1000 ground radar system as a monitoring tool, the effect after the emergency management for landslide monitoring, the monitoring data of landslide surface were obtained through the ground radar and combining the macroscopic investigation, analyses the stability of the landslide after emergency treatment, for landslide governance and road traffic provides scientific basis for recovery. At the same time, the application effect of ground-based radar in loess exposed area is verified, which provides a basis for the popularization and application of landslide emergency monitoring technology in Gansu Province. |
