微变雷达技术在公路边坡监测中的应用

Application of Micro-variable Radar Technology in Highway Slope Monitoring

近年来,高速公路位移变形监测成为预防公路地质灾害的最有效手段,但当前的自动化监测大多为点状监测,通过对监测数据的分析研究,结合现场岩土体情况,提前实现预警预报,因需要去高风险的滑坡核心区域安装设备,存在较大的安全风险。为解决这其中存在的风险隐患,在传统自动化监测技术的基础上,引入微变雷达技术对公路边坡进行抢险监测。实验验证表明,此技术实现了边坡的全天时、全天候、非接触的面域监测,也证实了微变雷达在边坡抢险中具有良好的适用性,为公路行业抢险监测提供了新的方法与思路。

In recent years,displacement and deformation monitoring of highways has become the most effective means to prevent geological hazards on highways.However,most current automated monitoring is point-based,which involves installing equipment in high-risk landslide core areas and poses significant safety risks.To address these risks,micro-variation radar technology is introduced into highway slope rescue monitoring based on traditional automated monitoring techniques.Experimental verification shows that this technology achieves full-time,all-weather,non-contact surface area monitoring of slopes,and confirms that micro-variation radar has good applicability in slope rescue.This provides a new method and approach for emergency monitoring in the highway industry.
